Abstract

This paper presents a small size UWB patch antenna with two notch filters. U-shaped and J-shaped slots are loaded in the patch of the antenna for WiMAX and WLAN frequency band rejection. The antenna is simulated using the commercially available CST Microwave Studio software. The slots dimensions are systematically adjusted and optimized to achieve the desired band rejection responses. The achieved results demonstrate that the antenna has good performance over the entire working frequency band (3.1 GHz to 10.6 GHz) except WiMAX (3.15-3.7 GHz) and WLAN (5.15-5.85 GHz) notched frequency bands. Moreover, the antenna was fabricated and the simulation results are experimentally validated. The measured results demonstrate a good agreement with the simulations.
