Abstract

This paper introduces an innovative circular microstrip patch antenna design featuring a defected ground structure (DGS) for enhanced wireless communication performance. With compact dimensions of 35 mm × 30 mm × 1.59 mm, the proposed antenna demonstrates a wide impedance bandwidth of 2.70 GHz (2.30-5.01 GHz) and consistent gain characteristics averaging 3 dBi. Simulation results obtained through CST Microwave Studio confirm the antenna's effectiveness for simultaneous operation in WLAN, WiMAX, and lower UWB frequency bands.
