Original Abstract

A 2x2 microstrip patch antenna array fed by a substrate-integrated-waveguide (SIW) feeding network for 24 GHz radar applications is proposed in this letter. The microstrip patches are aperture-coupled with the feeding network consisting of a perpendicular coax-to-SIW transition and two Y-junction power dividers. The antenna design is performed in the full-wave electromagnetic solver ANSYS HFSS and verified by measurement. At the operation frequency 24 GHz, a fabricated prototype has a gain of 11.1 dBi and a low side-lobe level below –22 dB in the E-plane and –33 dB in the H-plane.
