A Low Sidelobe Rotman Lens Antenna Feed by H-Plane Waveguide
A low sidelobe Rotman lens was developed that operates Ka band with 16 beams. The angular interval between beams is smaller than half power beam width. It was structured with H-plane waveguide. The sidelobe was reduced by cancelling patterns of adjacent two beam ports. It is proved in the testing result that the sidelobe is reduced about 10dB compared with no cancelling measure. The scale of lens is reduced obviously by metal posts phase shifter.
