Description
Antennesystem for ILS-kurssenderanlegg. Antenna system for ILS heading transmitter system.
Denne oppfinnelse angår en forbedring av antennesystemer for kurssenderanlegg i instrumentlandingssystemer (ILS) for fly-plasser. Slike antennesystemer er sammensatt av et antall enkeltantenner og blir plasert nær enden av den rullebane som anlegget skal betjene. This invention relates to an improvement of antenna systems for heading transmitter systems in instrument landing systems (ILS) for airports. Such antenna systems are composed of a number of individual antennas and are placed near the end of the runway that the facility will serve.
Det er ofte ønskelig at antennesystemet har en viss utstråling også bakover i forhold til rullebanen, slik at fly i tilfelle av behov for det, kan motta kursinformasjon i posisjoner bakover fra rullebanen. Det er kjent i forbindelse med slike antennesystemer å innrette disse slik at det blir oppnådd forskjellig kursbredde forover og bakover, nemlig slik at kursbredden bakover er større enn den forover. Den større kursbredde bakover er ønskelig fordi dekningsområdet utifrå rullebane-retningen blir større og mulig fordi kravene til nøyaktighet ikke er så store som i for-overretningen. It is often desirable for the antenna system to have a certain amount of radiation also backwards in relation to the runway, so that aircraft can, if necessary, receive heading information in positions backwards from the runway. It is known in connection with such antenna systems to arrange these so that a different course width forwards and backwards is achieved, namely so that the course width backwards is greater than that forwards. The larger course width backwards is desirable because the coverage area from the direction of the runway becomes larger and possible because the requirements for accuracy are not as great as in the forward direction.
Det er formålet med oppfinnelsen å fremskaffe et nytt antennesystem som på enklere og billigere måte enn de eksisterende systemer muliggjør, forskjellig kursbredde forover og bakover samt nøyaktig og kontrollerbar innregulering av de ønskede forhold for hvert tilfelle. It is the purpose of the invention to provide a new antenna system which enables, in a simpler and cheaper way than the existing systems, different course width forwards and backwards as well as accurate and controllable regulation of the desired conditions for each case.
I kjente antennesystemer for ILS-kurssenderanlegg brukes det separate enkeltantenner rettet bakover fra rullebanen for å oppnå den ønskede bakoverstråling. En slik løsning er således den eneste tenkelige i et kjent system hvor det som hovedantenner blir brukt dipoler arrangert foran et metalltrådnett. Et slikt arrangement vil gi altfor liten eller ingen stråling bakover til at kursinformasjon kan bli oppnådd i slik retning. En annen kompli-kasjon ved slike konvensjonelle systemer er at de separate antenner for bakoverretningen krever spesielt utstyr for passende matning av disse. In known antenna systems for ILS course transmitter systems, separate single antennas directed backwards from the runway are used to achieve the desired backward radiation. Such a solution is thus the only conceivable one in a known system where dipoles arranged in front of a metal wire mesh are used as main antennas. Such an arrangement will give far too little or no radiation backwards for course information to be obtained in such a direction. Another complication with such conventional systems is that the separate antennas for the backward direction require special equipment for suitable feeding of these.
Den løsning som foreliggende oppfinnelse går ut på, ba-serer seg på anvendelse av enkeltantenner som er innrettet til å The solution that the present invention is based on is based on the use of individual antennas which are designed to
gi tilstrekkelig utstråling og dermed kursinformasjon i retning såvel forover som bakover fra rullebanen med forskjellige ILS-kurs- provide sufficient radiation and thus course information in the direction both forward and backward from the runway with different ILS courses
bredde forover og bakover. Det nye og særegne som i første rekke er karakteristisk for antennesystemet ifølge oppfinnelsen, er at i det minste noen av enkeltantennene i systemet har et forover/ bakover-forhold som er forskjellig fra de øvrige enkelt- width forward and backward. The new and distinctive feature that is primarily characteristic of the antenna system according to the invention is that at least some of the individual antennas in the system have a forward/backward ratio that is different from the other individual
antenner s forover/bakover-forhold. antennae s forward/backward ratio.
Det er ved løsningen ifølge oppfinnelsen funnet mest hen-siktsmessig å modifisere bare noen få av de enkeltantenner som er plasert ytterst i systemet, dvs. lengst fra senterlinjen. I mange tilfelle vil det være tilstrekkelig bare å modifisere den ytterste antenne på hver side. For å oppnå en øket kursbredde bakover er det nødvendig å modifisere disse ytterste enkeltantenner slik at deres utstråling bakover blir mindre. Det er herunder av interesse å bemerke at for de aktuelle typer enkeltantenner - - og ganske særlig for de foretrukne' logperiodiske dipolantenner - vil strålingen forover ikke influeres merkbart ved endring av bakover-strålingen på denne måte. With the solution according to the invention, it has been found most expedient to modify only a few of the individual antennas which are placed at the outermost part of the system, i.e. furthest from the centreline. In many cases it will be sufficient just to modify the outermost antenna on each side. In order to achieve an increased course width backwards, it is necessary to modify these outermost individual antennas so that their radiation backwards becomes smaller. It is here of interest to note that for the relevant types of single antennas - - and quite particularly for the preferred 'log-periodic dipole antennas' - the forward radiation will not be noticeably influenced by changing the backward radiation in this way.
Selv om denne oppfinnelse med størst fordel anvender logperiodiske antenner som systemets enkeltantenner, er den ikke begrenset til denne antennetype. En annen type antenner som kan tenkes anvendt, er Yagi-antennen. Denne antennetype har imid-lertid den ulempe i denne forbindelse at den hittil ikke lar seg beregne nøyaktig på forhånd for oppnåelse av oppstilte krav, Although this invention most advantageously uses log-periodic antennas as the system's individual antennas, it is not limited to this type of antenna. Another type of antenna that can be used is the Yagi antenna. This type of antenna, however, has the disadvantage in this regard that it has so far not been possible to accurately calculate in advance to achieve the stated requirements,
f.eks. med hensyn til forover/bakover-forhold. Tilpasningen må e.g. with regard to forward/reverse ratio. The adaptation must
i hvert tilfelle skje eksperimentelt og dette kan være både kostbart og tidkrevende. in each case take place experimentally and this can be both expensive and time-consuming.
Med enkeltantenner i form av logperiodiske dipolantenner - som foretrekkes ifølge oppfinnelsen - blir de forskjellige" forover/ bakover-forhold fortrinnsvis oppnådd ved at én eller flere dipoler i fortrinnsvis hver logperiodisk dipolantenne har en lengde og/eller plasering langs matebommen som medfører avvik fra en eksakt logperiodisk struktur. Slike avvik kan fastlegges forholds-vis raskt og sikkert fordi den logperiodiske struktur eller opp-bygning kan beskrives temmelig nøyaktig matematisk. Ved modifi-sering av dipolers plasering langs matebommen blir disse parallell-forskjøvet i matebommens lengderetning. With single antennas in the form of log-periodic dipole antennas - which are preferred according to the invention - the different "forward/backwards" ratios are preferably achieved by one or more dipoles in preferably each log-periodic dipole antenna having a length and/or location along the feed beam which entails deviation from an exact logperiodic structure. Such deviations can be determined relatively quickly and reliably because the logperiodic structure or build-up can be described quite precisely mathematically. By modifying the placement of dipoles along the feed boom, these are shifted parallel in the feed boom's longitudinal direction.
Når det foretrekkes å anvende logperiodiske enkeltantenner When it is preferred to use log-periodic single antennas
i systemet ifølge oppfinnelsen, skyldes dette ikke bare at denne antenne-type beherskes matematisk, men også det forhold at logperiodiske antenner er lite påvirkelige av vær- og nedbørsforhold, f.eks. stor snedybde. For ytterligere å forbedre egenskapene i så henseende er det fordelaktig å kapsle matebommen med et vær-bestandig dielektrikum, f.eks. glassfiberarmert plast. in the system according to the invention, this is not only due to this type of antenna being controlled mathematically, but also to the fact that log-periodic antennas are little affected by weather and precipitation conditions, e.g. great snow depth. To further improve the properties in this respect, it is advantageous to encapsulate the feed boom with a weather-resistant dielectric, e.g. fiberglass reinforced plastic.
Til nærmere forklaring av oppfinnelsen skal denne i det følgende beskrives i tilknytning til tegningene. Figur 1 viser skjematisk og forenklet et grunnriss av et antennesystem ifølge oppfinnelsen med strålingsdiagrammer inntegnet. For a more detailed explanation of the invention, it will be described in the following in connection with the drawings. Figure 1 shows a schematic and simplified ground plan of an antenna system according to the invention with radiation diagrams drawn.
Figur 2 viser et grunnriss av en logperiodisk dipolantenne med avvik fra den.nøyaktige logperiodiske struktur. Figure 2 shows a plan of a logperiodic dipole antenna with deviations from the exact logperiodic structure.
Antennesystemet på figur 1 består av seks enkeltantenner The antenna system in Figure 1 consists of six individual antennas
1-6, f.eks. logperiodiske dipolantenner, som er anordnet side om side langs en linje T som danner en rett vinkel med rullebanens senterlinje S. Antennearrangementet er på kjent måte symmetrisk om senterlinjen S. For hver enkeltantenne er det med fullt opp-trukne linjer inntegnet et strålingsdiagram omfattende en forover-lobe henholdsvis lc, 2c osv. og en bakover-lobehenholdsvis la, 1-6, e.g. log-periodic dipole antennas, which are arranged side by side along a line T that forms a right angle with the runway center line S. The antenna arrangement is, in a known manner, symmetrical about the center line S. For each individual antenna, a radiation diagram comprising a forward -lobe respectively lc, 2c etc. and a backward lobe respectively la,
2a, 3a, 4a, 5a og 6a. For antennene 1, 2, 5 og 6 - som er de to 2a, 3a, 4a, 5a and 6a. For antennas 1, 2, 5 and 6 - which are the two
ytterste på hver side i systemet - er det dessuten med strekede linjer inntegnet bakover-lbber lb, 2b, 5b og 6b som er forskjellige fra bakover-lobene 3a og 4a. Antennene 1, 2, 5 og 6 er ifølge oppfinnelsen modifisert slik at deres opprinnelige bakover-lober la, 2a osv. er blitt endret til de med strekede linjer viste lober lb, 2b, outermost on each side of the system - there are also marked with broken lines backward lobes lb, 2b, 5b and 6b which are different from the backward lobes 3a and 4a. According to the invention, the antennas 1, 2, 5 and 6 have been modified so that their original backward lobes 1a, 2a etc. have been changed to the lobes 1b, 2b, shown in dashed lines.

Det forutsettes da at foroverstrålingen ikke. er blitt påvirket nevne-verdig ved modifiseringen av disse antenner. It is then assumed that the forward radiation does not. has been significantly affected by the modification of these antennas.
På figur 1 er det' videre med linjene 11' og 11" antydet In Figure 1, it is further indicated by the lines 11' and 11".
en vinkel C i retning forover. Denne vinkel skal illustrere kursbredden forover. Bakover er det tilsvarende inntegnet en kursbredde med vinkel A mellom linjene 13' og IS", henholdsvis en kursbredde B mellom linjene 12" og 12". Kursbredden A er den som man får når alle enkeltantenner har samme forover/bakover-forhold, an angle C in the forward direction. This angle should illustrate the course width ahead. Backward, a course width with angle A between the lines 13' and IS", respectively a course width B between the lines 12" and 12", is correspondingly drawn. The course width A is the one obtained when all individual antennas have the same forward/backwards ratio,
dvs. når ingen av enkeltantennene er modifisert som forklart ovenfor. I dette, tilfelle er,kursbredden forover lik den bakover, dvs. i.e. when none of the individual antennas have been modified as explained above. In this case, the forward course width is equal to the backward one, i.e.
A<=>C. A<=>C.
Hvis derimot antennene 1, 2, 5 og 6 er modifisert som forklart, slik at deres bakover-lober blir som tegnet med strekede linjer, vil kursbredde bakover bli større, hvilket er antydet med vinkelen B på figur 1. If, on the other hand, the antennas 1, 2, 5 and 6 are modified as explained, so that their backward lobes are as drawn with dashed lines, the backward course width will be greater, which is indicated by the angle B in Figure 1.
På figur 2 er det vist et eksempel på en type enkeltantenne som kan brukes i antennesystemet ifølge oppfinnelsen. Det er på figuren vist en logperiodisk dipolantenne 20 med syv dipolele- Figure 2 shows an example of a type of single antenna that can be used in the antenna system according to the invention. The figure shows a log-periodic dipole antenna 20 with seven dipole

er bare den ene halvdel tegnet inn. Dipolelement nummer fem regnet forfra (element 25) er her laget kortere enn en eksakt logperiodisk struktur ville tilsi,, og dette medfører en modifikasjon av den art som er omtalt ovenfor. Et slikt avvik fra den eksakte logperiodiske struktur resulterer i at antennen - som i sin nor- only one half is drawn in. Dipole element number five counted from the front (element 25) is here made shorter than an exact logperiodic structure would imply, and this entails a modification of the kind discussed above. Such a deviation from the exact logperiodic structure results in the antenna - as in its nor-

When using such a log-periodic antenna in the system in Figure 1, all individual antennas will thus preferably deviate from the strictly log-periodic principle, but the two outer

In that way, according to the invention, a change of the course width backwards in front is easily and cheaply achieved.
hold til den forover. hold on to it going forward.
Som et tallmessig eksempel på hva som er oppnåelig, kan As a numerical example of what is achievable, can
det nevnes at med en forkortelse av det viste element 25 i antennen 20 med ca. 12%, vil forover/bakover-forholdet gå ned fra en normal - og neglisjerbar - verdi (eksakt logperiodisk struktur) it is mentioned that with a shortening of the shown element 25 in the antenna 20 by approx. 12%, the forward/backward ratio will decrease from a normal - and negligible - value (exact logperiodic structure)
på ca. 30 dB til ca. 13 dB. Forkortelse av et slikt element med andre prosentdeler vil gi tilsvarende variasjoner i forover/bakover -forholdet. of approx. 30 dB to approx. 13dB. Shortening such an element with other percentages will give corresponding variations in the forward/backward ratio.
I det på figur 1 viste system vil man med seks identiske enkeltantenner med forover/bakover-forhold lik 13 dB, eksempelvis få en kursbredde forover lik kursbredden bakover på ca. 4° (A = C In the system shown in figure 1, with six identical single antennas with a forward/backward ratio equal to 13 dB, for example, a forward course width equal to the backward course width of approx. 4° (A = C
= ca. 4°). Hvis de to ytterste antenner på hver side, nemlig antennene 1, 2, 5 og 6 modifiseres slik at deres forover/bakover-forhold blir ca. 19 dB, vil kursbredden bakover eksempelvis øke til ca. 7 . = approx. 4°). If the two outermost antennas on each side, namely antennas 1, 2, 5 and 6 are modified so that their forward/backward ratio is approx. 19 dB, the course width backwards will for example increase to approx. 7 .
Det er klart at oppfinnelsen ikke er begrenset til de på tegningen viste utførelser og de ovenfor gitte talleksempler. It is clear that the invention is not limited to the embodiments shown in the drawing and the numerical examples given above.
Selv om det normalt vil være ønskelig å ha større kursbredde Although it would normally be desirable to have a larger course width
bakover enn forover, vil det omvendte også lett kunne oppnåes med den løsning som oppfinnelsen fremskaffer. Når det spesielt gjelder logperiodiske dipolantenner, er det efter ovenstående videre klart for en fagmann at foruten variasjon av antenne-elementenes lengde, vil variasjon av elementenes plasering langs matebommen kunne brukes til å frembringe de nevnte avvik fra den eksakte logperiodiske struktur. backwards than forwards, the reverse will also be easily achieved with the solution provided by the invention. When it particularly concerns logperiodic dipole antennas, it is further clear to a person skilled in the above, that in addition to variation of the length of the antenna elements, variation of the placement of the elements along the feed boom could be used to produce the aforementioned deviations from the exact logperiodic structure.
