In this paper, a simple diamond-shaped slot antenna working in the millimeter-wave 5G band of 60 GHz, with circular polarization (CP), high radiation efficiency and broadband performance both in matching and axial ratio (AR) is presented. The antenna is implemented in Gap Waveguide (GW) technology, namely Ridge Gap Waveguide topology. The simulation results demonstrate a fractional bandwidth of 14.52% considering both the reflection coefficient and AR (|S11 < -10 dB and AR < 3dB) extending from 60.5 to 69.3 GHz (> 8 GHz) The maximum gain of the system is around 7 dB, with an efficiency close to 98%. The antenna was manufactured and measured experimentally. The results obtained show a good agreement with the simulations.
