WIDE-BASE UPPER LOAD ANTENNA Russian patent published in 1996 - IPC

FIELD: radio engineering. SUBSTANCE: device has current-clipping resonant two poles which are connected along vertical conductor, and tube frame with matching unit. Tuning element is inserted in each current-clipping two-pole. Matching element is designed as circuit which consists of inductance coil, capacitor and pieces of long lines. Tuning elements may be designed as parallel LC-circuits. Current-clipping two-poles may be designed as short-circuited coaxial pieces. In this case tuning elements may be designed as reactive LC-circuits or as by shunts or as by dielectric insertions. EFFECT: increased functional capabilities. 7 cl, 6 dwg
