DIRECTOR ANTENNA Russian patent published in 2000 - IPC

FIELD: transceiver antennas for radio systems such as television receiving antennas. SUBSTANCE: antenna whose directivity is up to 12 dB has metal pivot carrying on its ends reflector and director built up of metal rods arranged in one plane, both secured thereon perpendicular at their centers; active radiator of similar circular tubular frames with gaps in one plane perpendicular to pivot which are joined together by means of tubular connector at points diametrically opposite to gaps so that line crossing centers of gaps and tubular connector axis form symmetry axis of radiator; interface with input in the form of coaxial connector which is secured in center of tubular connector perpendicular to frame plane; inner conductors routed inside halves of both frames arranged on one side of radiator symmetry axis as well as inside halves of tubular connector and connected on one end to central conductor of interface output and on other end, to opposite ends of frames in gaps. Tubular connector is mounted on pivot perpendicular to location plane of reflector and director. EFFECT: improved directivity of self-centering antenna. 3 cl, 4 dwg
