Abstract:

Recent research show that some parameters such as the shape of antenna patch and ground plane when geometrically altered produces changes in the return loss and consequently in the resonant modes. This paper presents a circular rectangular microstrip antenna modified with the technique of inserting slots in the ground plane in order to alter the specific behavior in the resonant frequencies. The antenna has been designed and simulated using ANSOFT HFSS simulator. It make use of FR4 as substrate with dimensions 50mm×40mm×1.2mm. The circular rectangular antenna resonates at 2.4 and 5.5GHz frequencies for WiFi applications according to IEEE standards, while the modified ground plane version resonates through a band of frequency (9.92-11.46 GHz) in X band.
