In this study, a 60 GHz optically transparent microstrip (OTM) patch antenna array is designed, fabricated and measured. Gold meshes are implemented for the two layers of the antenna. A numerical parametric study on the positioning of the two meshed layers is performed to give design considerations and optimise both the electromagnetic and optical performances of OTM antennas at 60 GHz band. The simulation and measured results of the OTM antenna with a theoretical maximum transparency up to 74.6% are compared with a light reflecting reference antenna. Both antennas have similar reflection coefficients and radiating performances. This study provides practical design rules to fabricate high gain OTM antennas with performances similar to those of standard topologies at 60 GHz band, with the addition of high optical transparency.
