Description
Technical field
The utility model relates to the antenna in a kind of communications service, particularly a kind of broadband high-gain vertical depolarized omnidirectional antenna.
Background technology
Along with the fast development of mechanics of communication, the Personal Handyphone System various places that spread all over the country already, but it does not possess the function general with the Internet, then will spend huge input if will rebuild WLAN (wireless local area network); Third generation mobile in recent years (3G) progressively begins to build in some key cities of China, drops into very big fund again and builds numerous base stations and dispose special antenna; TV programme is seen for making national vast town and country every household by the Chinese government, begun " the village village is logical " engineering several years ago, transmitting television signals also will be come by microwave multiple access distribution system (MMDS) in some remote countrysides, mountain area, mining area, also will set up special antenna facility.These several communication systems all use own custom-designed antenna, and each architectonical does not have interoperability, and all will build separately, and costs such as its manufacture, installation, maintenance are high always.So, only develop and just can satisfy the active demand that the common antenna that uses of these communication systems has become market with a kind of structure.
Summary of the invention
The technical problems to be solved in the utility model is for overcoming the deficiencies in the prior art, proposes a kind of, broadband high-gain vertical depolarized omnidirectional antenna that can also be used for third generation mobile antenna for base station and MMDS transmitting television signals shared applicable to Personal Handyphone System and WLAN (wireless local area network).
Technical solution of the present utility model is: four antenna plate that are printed on micro-strip oscillator constitute four directional antennas with four microstrip-fed wiring board vertical fixing respectively, these four directional antennas surround square tube again, and by little four road power splitter feeds of being with of the 90 ° of phase differences of a stepping that are positioned at the square tube below that microstrip-fed wiring board surrounds.
Further technical solution of the present utility model is: said little four road power splitters of being with are a cylindrical shape, the merit parallel circuit is printed on drum surface, 90 ° of the steppings successively of the phase place of its four input ports, this little square tube below that surrounds by four microstrip-fed wiring boards that is placed on four road power splitters.The grounding arm of the micro-strip oscillator that antenna plate is simultaneously printed directly with little band ground welding of microstrip-fed wiring board, and the band line of the feed band line of the micro-strip oscillator that another side is printed by lead and microstrip-fed wiring board welds.
Because the utility model has fully taken into account the specification requirement of Personal Handyphone System and WLAN (wireless local area network) and third generation mobile antenna for base station and MMDS TV transmission program when design, synthesize omnidirectional antenna with the wide band high-gain directional antenna, realized the high-gain and the broadband of omnidirectional antenna; Adopt four road power splitter feeds of 90 ° of phase differences of stepping according to this again, the reflection of each directional antenna is cancelled each other, and is easy to realize wide band impedance matching; Feeding network adopts and does not wait the feed that is in parallel, and the wave beam inclination angle is controlled easily, can realize high-gain; Unique micro-strip oscillator need not to allocate the broad band performance that can guarantee directional antenna; The micro-strip oscillator antenna plate is vertically connected on the microstrip-fed wiring board, compact conformation, good rigidly, long service life.
By above technical characterictic and as can be seen to the technical performance index of the actual test of this antenna, the utility model has had bigger technological innovation on the basis of original several antennas, only the antenna with a kind of structure just can transmit Personal Handyphone System, WLAN (wireless local area network), third generation mobile and MMDS signal, it is mutual general that several persons have been realized, promote the performance of China's communication system, the investment that the saving system builds improves the level of IT application, benefits numerous people.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings, the utility model mainly is to be made of four antenna plate that are printed on micro-strip oscillator 51, four microstrip-fed wiring boards 2 and one little four road power splitters 3 of being with of 90 ° of phase differences of stepping successively.Wherein, four antenna plate 1 are vertically fixed on respectively on four microstrip-fed wiring boards 2, constitute four directional antennas, constitute an omnidirectional antenna again by four directional antennas.Two limits that each microstrip-fed wiring board 2 is adjacent are orthogonal again to surround a square tube shape, and the one side that microstrip-fed wiring board 2 contacts with antenna plate 1 is little band ground, and inside one side is band line face.90 ° of the steppings successively of the square tube shape below that four road power splitter 3 cylindraceous place microstrip-fed wiring board 2 to surround, the phase difference between the adjacent input port of this four road power splitter 3.The grounding arm of the micro-strip oscillator 5 that the one side of antenna plate 1 is printed directly with little band ground welding of microstrip-fed wiring board 2, and the band line of the feed band line of the micro-strip oscillator 5 that another side is printed by lead and microstrip-fed wiring board 2 welds.Outside this antenna, also be provided with a radome 4.
This antenna is 90 ° wide band high-gain directional antenna with four azimuth plane lobe widths, make their beam position interlace 90 °, differ 90 ° of feeds successively by four road power splitters 3 again, their formate field intensity is exactly that each is to uniformly, promptly form omni-directional pattern, thereby constitute the wide band high-gain omnidirectional antenna.Wherein the wide band high-gain directional antenna be exactly the wideband microband oscillator be the linear array of the microstrip feed network feed of radiating element.
This micro-strip oscillator need not to allocate, and can guarantee the broad band performance of directional antenna.And the feeding network employing does not wait the feed that is in parallel, wave beam inclination angle to control easily, can realize high-gain.
