Abstract: In this article single patch antenna with multiple feed lines is presented. The antenna is tested with four ports each separated at 90 degrees. The ports separated at 180 degrees have the same effects and same polarisation. The S-parameter of port 1 and port 2 are same due to horizontal polarisation then port 2 and port 4 are same due to vertical polarisation. The Port 1 and Port 3 resonates at frequency of 2.092GHz and 4.563GHz. It covers applications of UMTS (1.885GHz – 2.2 GHz) and C band (4 GHz – 8GHz). The Port 2 and Port 4 resonates at frequency of 1.66GHz and 5.155GHz. It covers applications of GPS (1.565GHz – 1.665GHz) and WLAN (5 GHz – 6 GHz). The return loss of the frequencies is less than10dB. The isolation among the ports are less than 15 dB.
Keywords: Patch Antenna, Microstrip Antenna, Rectangular Patch and Multiple Feed Antenna.
