DOUBLE-LOOP ANTENNA Russian patent published in 2001 - IPC

FIELD: transceiver loop antennas for miscellaneous radio systems including television ones. SUBSTANCE: antenna has two similar annular tubular loops placed in same plane, interconnected through tubular jumper, and provided with gaps and coaxial matching device arranged in diametric opposition to junction points of loops; matching device is mounted in center of tubular jumper perpendicular to loop surfaces. Conductors mounted inside loop halves located on one side of antenna center line and inside halves of tubular jumper are secured within these halves by means of insulating washers and connected on one end to central conductor of coaxial matching device and on other end, to opposite ends of gaps in metal plugs. Center line of antenna crosses centers of gaps and tubular jumper axis. EFFECT: enhanced directivity factor of self-balancing antenna. 4 cl, 5 dwg
