A wearable version of Fabry-Perot antenna is presented. This is a simple way of designing a medium- to high-gain antenna with low back radiation. The study of the effect of antenna bending in the performances is presented. Besides, the replacement of a superstrate layer by a metallic frequency selective surface is proposed. In this way, there is no need of finding a specific material and thickness for a targeted gain and frequency. Experimental validation confirms the viability of this design.
