In this article a compact miniaturized wearable antenna with the appearance of a button on clothing for WLAN applications is presented. The radiating elements of the antenna are made of copper sheet, whilst a transparent acrylic fiber sheet material is used as substrate and fed by a coaxial line through the ground plane. The proposed antenna is simulated by Ansoft HFSS FEM based EM simulator and has been optimized to operate within the WLAN frequency bands with centre frequency of 5.25 GHz (5250-5850 MHz). A split ring-shaped slot based frequency selective surface (FSS) is designed to enhance the gain of the proposed antenna. The peak gain of the antenna is enhanced from 2.1dBi to 5.1dBi with the superstrate along with a bandwidth enhancement of 290MHz. The antenna gets miniaturized around 34% by the slit.
