A 95–110GHz Fully Metallic Four-Beam Passive Array Antenna with High Gain and High Efficiency
This work reports the experimental demonstration of a 100GHz-band fully metallic waveguide multibeam antenna fed by the E-plane groove gap waveguide (GGW) Butler Matrix. The E-plane property of the Butler matrix helps in its direct interconnection with the H-plane horns without any E- to H-plane waveguide transformer. The design concept has been verified by prototyping and it has been demonstrated that the proposed multibeam antenna can work over 95–110 GHz with a peak gain of 16.6 dBi, peak efficiency of 89%, and beam coverage of <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$-46^{\circ}\sim 46^{\circ}$</tex>.
