Abstract

In this paper, a compact CPW-fed antenna for 5 GHz (5.15-5.35 GHz, 5.725-5.825 GHz) band WLAN applications is presented. The designed antenna's shape is step structure. The antenna is fabricated and measured into FR-4 substrate of dielectric comstant 4.2 and thickness 1.0 mm with optimized parameters obtained by simulation. We confirm that it is operated as antenna for WLAN applications by obtaining the measured return loss level of < -10 dB in 5.133-5.982 GHz. The dimensions of the antenna ($20.0{\times}16.0{\times}1.0mm^3$) shows an compactness of about 67.17% with respect to a conventional folded slot antenna.
