Single Layer Antenna based on Gap Waveguide Technology with Dual-Circular Polarization for 60-GHz Band

Paper in proceeding, 2023

A dual-circularly polarized antenna element based on E-plane groove gap waveguide (GGW) for 60 GHz applications is presented in this work. The simulated return loss of the antenna is better than -10 dB for both polarizations in the working frequency bandwidth of antenna covering from 58 GHz to 62 GHz. The axial ratio of the proposed antenna is better than 2.5 dB in the whole bandwidth. The simulation results prove that the proposed antenna element is a good candidate to design larger array with dual circular polarization for different wireless applications at millimeter wave frequency range.
