Abstract

AbstractThe gain enhancement of a rectangular open-ended waveguide (OEW) with a finite circular ground plane in the mmWave frequency range is presented in this paper. The circular ground plane, made of dielectric (FR-4) sandwiched by two perfect electric conductor (PEC) sheets, is placed on the open end of a standard WR-28 waveguide. Two optimized slots are etched out on the radiating front side of PEC sheets of the circular ground plane such that the slots expose the FR-4 substrate. In this way, the OEW with a slotted ground plane provides a gain of 14.93 dBi as compared to the gain of 5.74 dBi by a standard WR-28 waveguide. The full-wave simulator, Ansys HFSS, is used to carry out simulations and optimizations of the antenna structure.Keywords5G communicationsGainGround planemmWavesOpen-ended waveguide (OEW)Perfect electric conductor (PEC)
