CPW-Fed Transparent Antenna Array Using Metal Mesh

Increasing the deployment density of the indoor base stations is a way to deal with the problem of low transmission efficiency of high-frequency communication indoors in the future. To reduce the space occupation and virtual influence of the indoor base station, a coplanar waveguide (CPW)-fed transparent antenna array (TAA) is proposed. The TAA is comprised of 4 CPW-fed antenna units and a standard glass substrate. The gain is improved by array structure to 7.6 dBi. The transparency of the antenna achieves 80%. It achieves more than 90% efficiency. The TAA operates at the bands of 2.12-2.5 GHz.
