Abstract :
We propose a new configuration of one radiating slot and two reflection-canceling slots for degree linear polarization in post-wall waveguide fed parallel plate slot arrays. Uniform aperture field has been obtained in a 76 GHz model antenna with a 5 cm-square area. Cross polarization is suppressed below -26 dB in the boresight. A peak gain of 29.8 dBi is realized with 46.4% efficiency.
