WIRE-RANGE CIRCULAR ANTENNA ARRAY Russian patent published in 1997 - IPC

FIELD: electrical engineering. SUBSTANCE: antenna array has at least one planar dielectric base with metallized layers incorporating excitation system and radiating aperture coupled with it and formed from horn radiators arranged in several levels; radiating aperture of antenna array forms closed second-order curve such as circumference; its metallized layers incorporating radiating aperture are arranged outside around dielectric base carrying excitation system and are connected at points of level discontinuities. If more than one antenna array is installed, they form volumetric assembly of intercoupled antenna arrays. EFFECT: enlarged scanning sector of space amounting to 360 deg and reduced loss in adding system. 3 cl, 4 dwg
