Design of Transparent Rectangular Patch Antenna for 5G Applications

Abstract

Transparent antennas are meant for their optical transparency. This paper analyzes the rectangular patch antenna designed using meshed conductors and solid ground planes. Meshing the antennas makes it as optically transparent and the antenna’s transparency is based on the mesh geometry. Even there is a tradeoff between the antenna’s efficiency and the visual see-through ability of the patch antenna with meshed structure, it is able to tune the antenna by refining mesh lines. Material handling, fabrication process and the increased impedance are the important factors limiting the refining of the mesh lines, which also cause loss in efficiency of the antenna. Both the performance and antenna transparency is improved by a mesh refined with small line width (q). Also, by removing certain mesh lines, the antenna transparency is improved without affecting the antenna efficiency. This paper briefly explains the relation between the gain, transparency and the mesh structure of the antenna.
