Slot Antenna Array Unit Cell Directly Fed by Inverted Microstrip Gap Waveguide

• Inverted microstrip gap waveguide is mechanically flexible millimeter wave transmission line. This paper describes a single-layer slot antenna array unit cell at 60-GHz designed by using this inverted microstrip gap waveguide technology. This antenna unit mainly consists of a 2×2 slot layer and corporate-feed networks. The unit-cell shows more than 14.6% bandwidth over 57-66 GHz band with 10-dB return loss. Infinite array environment has been utilized later to determine overall efficiency for bigger 16×16 antenna array which is around 70% with a directivity value of 33.5 dBi between 57-66 GHz.
