Abstract: A circular monopole antenna with coplanar waveguide feeding is designed for wideband applications. Different electromagnetic bandgap structures are placed beneath the antenna ground plane to improve the gain and the radiation efficiency. The depicted model occupies the dimension of 50X50X1.60 mm on FR4 substrate with dielectric constant of 4.3. Aerial operating in the dual band of 1.5-3.6 GHz (GPS, LTE, Bluetooth and Wi-Fi applications) and 4.8-15 GHz (WLAN, X-Band and Satellite communication applications) with bandwidth of 2.10 and 10.20 GHz respectively. The final novel antenna design provides good correlation with simulation results.
Keywords: Bandwidth enhancement, Coplanar waveguide feeding (CPW), Monopole.
