Screen-Printed Dual-Band Flexible Frequency Selective Surface for 5G Applications

A Polyethylene Terephthalate based screen printed millimetre wave dual band (13.0/26.0 GHz) frequency selective surface is presented. The experimental prototype demonstrates validity of the design methodology, stability of angular response to the incidence angle of excitation, and feasibility of operating surface in the close proximity of radiation source. The resulting Frequency selective surface is low cost, flexible, conformal, optically transparent, and biodegradable that can be used in 5G indoor interference mitigation and frequency reuse applications.
