Aperture-Coupled Microstrip Patch Antenna Fed by Orthogonal SIW Line for Millimetre-Wave Imaging Applications
A new microstrip patch antenna feeding technique for millimetre-wave imaging applications is proposed. The technique utilises a substrate integrated waveguide line that orthogonally feeds the patch antenna through a coupling aperture. A rectangular microstrip patch antenna was designed to operate at 32 GHz. Measurement and simulation results for rectangular patch antenna are presented showing good agreement with 9% bandwidth (|S11| < -10 dB). The aperture-coupled rectangular patch antenna provided 5.5 dBi gain and 72% efficiency at the design frequency. Finally, the rectangular patch antenna is used for near-field and wideband synthetic aperture radar imaging to demonstrate the potential of the proposed antenna for imaging applications at millimetre wave frequencies.
