摘要: A new microstrip patch antenna feeding technique for millimetre-wave imaging applications is proposed. The utilises a substrate integrated waveguide line that orthogonally feeds the through coupling aperture. rectangular was designed to operate at 32 GHz. Measurement and simulation results are presented showing good agreement with 9% bandwidth (| S 11 | <; -10 dB). aperture-coupled provided 5.5 dBi gain 72% efficiency design frequency. Finally, used near-field wideband synthetic aperture radar demonstrate potential of proposed millimetre wave frequencies.
