Development of Flexible & Quasi-Optically Transparent CPW Antennas for 5G by Meshing Construction

This paper presents optical transparent CPW antennas designed for 5G telecommunications obtained by an additive printing process. This optical transparency has been obtained by meshing the antenna. The influence of the meshing strategy on the antenna performances is explored, by investigating two geometrical models of antennas and in three different meshing. The adaptation, radiation performance and optical transmittance have been characterized. The best trade-off between transparency and radiation performance is presented through a plot connecting the realized gain and the optical transparency. The square meshing features the best trade-off with more than 65% of optical transparency for 2 dBi in realized gain.
