STRIPLINE ANTENNA Russian patent published in 1998 - IPC

FIELD: antenna equipment. SUBSTANCE: invention is intended for usage in communication and radiolocation equipment as single wide-band radiator and as element of low-profile array. Stripline antenna includes dielectric substrate, metal screen, main stripline radiator one edge of which is shorted to metal screen linked to supplying feeder and several additional stripline radiators one edge of which is shorted to metal screen too that are arranged on two opposite sides of main stripline radiator at small distances not exceeding several hundred fractions of wave length and intercoupled by straps ensuring required communication. Width of additional stripline radiators does not exceed several hundredth of wave length. They are inclined relative to main stripline radiator, are resistively intercoupled and connected to main stripline radiator on sections of side walls bordering on shorted edges and short-circuiting switch is common for all radiators By proper selection of number and resonance frequencies of additional stripline radiator, positions of straps and values of coupled sections of side one can obtain operational band of frequency up to value with overlap of 2:1. In this case dimensions in plane of substrate does not exceed several tenth of middle wave length and thickness would not exceed one or two hundredth. EFFECT: expanded working band of frequencies with dimensions of stripline antenna not exceeding several tenth of wave length. 1 cl, 3 dwg
