Wideband Dual-polarized Array Antenna on Dielectric-based Inverted Microstrip Gap Waveguide

Paper i proceeding, 2019

A wideband dual-polarized planar array antenna is presented in this paper. The proposed array antenna consists of 8 × 8 bowtie antennas and dielectric-based inverted microstrip gap waveguide network. It is composed of multilayer substrate which can be fabricated by low cost PCB process. The simulated results show that the proposed array achieves a relative impedance bandwidth of 54.2% from 19.2GHz to 33.5 GHz for both polarizations with VSWR of 2.
