Abstract

A microstrip line fed compact monopole antenna is presented for the WLAN and WiMAX applications. The proposed antenna has a compact size of dimensions 34 × 20 × 1.6 mm3. A stepped shaped defected ground plane is used for the bandwidth enhancement. The parametric study is performed to obtain the best results for the design process of the antenna. The effect of asymmetric U-shaped strip and step slots in the ground plane provide an enhanced bandwidth. The antenna gives the measured impedance bandwidth of 105.21% (2.23–7.18 GHz). The simulated antenna gain is varying in the range of 2.39–4.68 dBi for the entire band of operation. Radiation efficiency is higher than 75.0% throughout the entire operating band. Measured radiation patterns are almost omnidirectional in H-plane and dumbbell shape pattern in E-plane. The antenna parameters are calculated using CST Microwave Studio and the simulated results are validated with the measured results.
