MOBILE WIDE-BAND UNTUNED ROD ANTENNA Russian patent published in 2004 - IPC

FIELD: radio engineering; mobile antennas for high-frequency radio transceiving centers. SUBSTANCE: antenna has main antenna elements mechanically coupled with antenna mast of height h and mast lift through support insulator, n working antenna curtains assembled of antenna strands disposed along generating lines of two right cones of different height joined together through their bases; top and bottom ends of N working antenna curtains are electrically interconnected through top and bottom collecting rings, respectively; bottom collecting ring is first feed point of antenna and its second feed point is where ends of counterpoises uniformly arranged about antenna are joined together; mast is held in vertical position by means of steel guy rope sectionalized by insulators and terminated with adjusting log-line; each of N working antenna curtains is split through height of 2h/s and complex matching load of parallel-connected non-inductive resistors and inductance coil is inserted in open circuit formed by split; antenna mast is split structure with M elbows; mast elbow is made in the from of metal tube and insulating tip with drilling that provides for mechanical joint between mast elbows and insulates these elbows from each other; counterpoises are uniformly arranged about antenna base; they are made in the form of tracks, 50 to 60 cm wide, woven of insulated wires, (0,3-0,5)λ_max long. EFFECT: enhanced radiation efficiency of mobile antenna along terrain. 1 cl, 5 dwg
