A Multi Beam Slot Array Antenna Fed by Contactless Multi-Layered 4x8 Buttler Matrix Using Gap Waveguide Technology for 60GHz Fixed Wireless Access Applications
Paper in proceeding, 2023

A multi layered multi beam antenna design based on gap waveguide technology is presented in this work. In the proposed antenna a 8x10 slot array is used as the antenna aperture, however the beam forming network (BFN) consists of a multi layered 4x8 Buttler matrix realized using both ridge gap waveguide (RGW) and groove gap waveguide (GGW) technologies. The proposed structure is composed of five unconnected layers which can be simply assembled using screws and guiding pins without any need of electrical contact in accordance with the contact-less assembly feature of gap waveguide technology. The designed antenna shows proper radiation performance including low side lobes and flat gain response which can be applied for access points in fixed wireless communications operating at 60GHz. Also the S11 remains below -10dB for the input ports within the frequency range of 5964-GHz. The simulated gain for the array is 25dBi at bore sight and 22 dBi when the +/- 45 degrees beam is excited.
