Highly Transparent and Efficient Flexible Antenna for Vehicle-to-Everything (V2X) Applications

This paper presents a single-sided planar transparent monopole antenna for vehicle-to-everything application. The fundamental limiting factor for the antenna's efficiency is studied, and a simple yet effective antenna topology as well as methods to improve antenna's efficiency are presented. Low-cost fabrication methods are proposed and the antenna prototypes are projected to have optical transparency as high as 90% and efficiency higher than reported prior art.
