ANTENNA ARRANGEMENT FOB WIRELESS TELEGRAPH.
Application filed September 3, 1821. Serial No. 498,485.
To all whom it may concern:
Be it known that I, Orro VON BnoNK, citizen of the German Republic, residing at v Berlin, Germany, have invented certain new and useful Improvements in Antenna Arrangements for Wireless Telegraphy (for which I have filed an application in Germany June 5, 1917, Patent No. 300,782), of which the following is a specification.
This invention relates to radio signalling systems and particularl to a method and apparatus for eliminatlng undesirable effects of the antenna masts.
The great height of the masts used for radio antenna makes it necessary to provide relatively great mechanical firmness. It is therefore necessary to make the masts almost entirelv of metal. The masts are a troublesome necessity in the alternating field of the antenna as they produce distortion in the path of the lines of force between the antenna and its surroundings which unfavorably influence the radiation and produce currents in the masts, which, depending on the resistance resent result in losses and diminish the e ectiveness of the entire antenna arrangement. To prevent these, the masts are usually separated from the ground by means of insulation but it is difiicult to maintain the insulation permanently good.
The present invention discloses a further.
means to counteract the efi'ects mentioned as will be hereunto described. The mast is u subjected to an electromotive force by means of an auxiliary source of energy drawn from the high frequency source and having the\ phase and distribution substantially ual to the electromotive force in the neigh r- 0 ing dielectric. The lines of force from the dielectric entering into the mast are thus reduced to a minimum so that the enlatter is coupled with a second coil S and from this the auxiliary energy is sulpplied to the mast. If S is uncoupled from then a 'current flows through the mast and feeding conductor, the value of which can be determined on the meter H. By correct coupling of S and L and proper electrical values of the current path comprising the earth mast and dielectric an electromotive force of the proper phase and amplitude can be impresed on the mast so that the current in it will be a minimum.
Having described my invention, what I claim is:
1. In radio signalling systems having an antenna supported by a conducting mast, means for impressing an electromotive force on the mast to substantially prevent induced currents therein.
2. In radio signalling systems having an antenna supported by a conducting mast, means for impressing an electromotive force on the mast substantially equal and opposite to the electromotive force normally 1nduced in the mast by the antenna.
3. In radiosignalhng systems having an antenna supported by a conducting mast, means for impressin an electromotive force on the mast substantially equal and opgosite to the electromotive force no'rmall in need in the mast by the antenna, sai electro: motive force being derived from said Inf tenna system. a
4. In radio signalling systems having an antenna supported by a conducting mast insulated from the earth, means for impressing an electromotive force on the mast to an stantially prevent induced currents therem 5. In radio signalling systems having an antenna supported by a conductin mast insulated from the earth, means or impressing an electromotive force on the mast substantiall equal and uapposite to the electromotive orce norm, mast b theealnknafiaidelgclrnromotive force bemg eriv m e an a system.
In testimony whereof I aflix the signature.
