DUAL-BAND SPIRAL ANTENNA

机译:双频螺旋天线

摘要

FIELD: antenna engineering. SUBSTANCE: antenna has two monobander sections each incorporating excitation circuit, grounded layer disposed in opposition to excitation circuit, and group of one or more radiators extending from excitation circuit. One novelty of invention is that contact is extended from excitation circuit of one of monobanders and ensures excitation of the latter. Contact also provides for passing current from radiators of second monobander along its axis so as to increase energy radiated in directions perpendicular to this axis. Another novelty of invention is that grounded layer of one of monobanders is used as short-circuiting ring for other monobander. EFFECT: provision for operation in two frequency bands. 25 cl, 23 dwg
