Waveguide Slot Array Antenna with a Hybrid-Phase Feed for Grating Lobe Reduction
The design of a 112-element millimeter-wave waveguide slot array antenna to reduce the grating lobe level is presented. A hybrid-phase feeding technique combining a cophase feed and an alternating-phase feed is applied to facilitate the suppression of grating lobes. In addition, a stepped feed waveg...
