Abstract

The low loss microstrip gap waveguide provides an easy and suitable solution to be used as feed network for antennas at high frequency. This paper presents the design of a slot coupled dual-mode horn element fed by microstrip gap waveguide for array applications at 60 GHz. The directive dual mode horn is used to reduce the grating lobes which are generated when the slot array elements have a distance bigger than lambda. Simulation results of the proposed design are presented in terms of return loss and grating lobe level.
