Summary:
The authors design the sidelode suppression in the 60GHz corporate-feed double-layer waveguide slot array antenna. The first sidelobes can be suppressed to -24dB, however -22.6dB sidelobes are observed in 30-40-deg. direction because the coupling slot in the bottom layer excites 2x2 radiating slots in the top layer with equal amplitude.
