BROADBAND LOOP ANTENNA Russian patent published in 2003 - IPC

FIELD: antenna equipment employed in radio communication, radio navigation, radio direction finding, television and broadcasting. SUBSTANCE: given broadband antenna includes two conductive loops placed in one plane and oriented with their ends in opposition, two identical conductive arc-shaped straps located in plane of loops and directed with convexity inside loops, matching transformer having two anti-phase inputs connected to first ends of loops and network comprising resistor and induction coil connected in series and placed between second ends of first and second loops. Ends of first and second straps are connected to conductors of first and second loops at distances correspondingly of (0.08-0.12)P and (0.32-0.48)P from first ends of loops, P being parameter of individual loop. EFFECT: diminished frequency dependence of impedance of antenna and its raised sensitivity. 5 cl, 1 dwg
