DIFFERENTLY POLARIZED PLANAR ANTENNA ARRAY Russian patent published in 2000 - IPC

FIELD: radio engineering. SUBSTANCE: antenna array designed for use in transceiver systems operating either within broad frequency band or at high transmit-receive frequency separation has rectangular-shape radiators with holes made directly under them on insulating board, and feed arranged on inner side of insulating board with its inputs connected to outputs of two power systems; probes are placed between radiators and feed; matching devices made in the form of insulating disks are coaxially arranged between probes and insulating board. EFFECT: extended operating frequency band both for radiation and ellipticity. 7 cl, 4 dwg
