Abstract
In wireless communication systems, patch antennas are most commonly used. A primary disadvantage of the patch antennas is their restricted bandwidth (<5%). This paper presents the design of a rectangular patch microstrip antenna for UWB applications using the partial ground plane technique with a single rectangular slot on the upper edge of the partial ground plane and right-angle triangular slots on the lower corners of the patch, which has been designed to overcome this impediment. The suggested design has an impedance bandwidth of 19.91 GHz around the six resonance frequencies of 3.4 GHz, 6.2 GHz, 8 GHz, 11.40 GHz, 17.40 GHz, and 21.40 GHz. This is about 13.54 times higher than the bandwidth of a traditional rectangular patch antenna (bandwidth =1.47 GHz). This antenna can be used in a wide variety of wireless applications such as X band, C-band, Ku band, S-band, STM band, WiMAX, WiFi, WLAN, radio astronomy, military communications, communications and sensors, positioning and monitoring, radar and satellite communication applications. HFSS simulation software has been used for the simulation of the propounded design.
