Abstract

In the present paper, a microstrip line fed compact monopole printed antenna is designed for Bluetooth, WLAN and WiMAX applications. The designed antenna has a compact size of dimensions 34 × 20 × 1.6 mm3. The proposed antenna comprises asymmetric U-shaped radiator embedded with a T-shaped strip in the middle of the patch. Stair shaped defected ground plane with rectangular slit is used for the bandwidth enhancement. The antenna design achieves the maximum impedance bandwidth of 107.35% (2.27–7.53 GHz). Radiation efficiency is higher than 70.0% throughout the entire operating band. The simulated and measured realised antenna gains are in good agreement and vary in the range of 2.14–4.83 and 2.20–4.91 dBi respectively. Radiation patterns are almost omnidirectional in H-plane and bidirectional pattern in E-plane. The antenna characteristics are calculated using CST Microwave Studio and the results are compared with the measured results.
