Abstract

A unique miniaturized and optimized Multiband coplanar waveguide (CPW-fed) antenna for modern wireless communication is presented. A new technique of using a Modified Ground Structure (MGS) and Frequency Shifting Strips (FSS), along with Defected Ground Structure (DGS) and Metamaterial (MTM) loading have been employed in the design to achieve the Multi-frequency operation. The proposed antenna generates four separate impedance bandwidths and covers the minimum required frequency bands of GSM 1800/1900, Wi-Fi/WLAN 5.2/5.5 GHz and WiMAX 3.3/10.3 GHz. The antenna is relatively small in size 17×20 mm2 and operates over the frequency ranges of 1.45–2.08, 2.87–3.44, 5.01–5.58, and 8.89–10.69 GHz. The designed antenna was simulated using the Ansoft HFSS, a FEM-based simulator. This paper presents the simulated characteristics of antenna including the reflection coefficient, gain, radiation efficiency, radiation pattern, impedance bandwidth, VSWR, the surface current and electric field distributions. Antenna’s key structural parameters and their effects on the antenna performance were also studied.
