This study targets do design a square ring patch antenna of size dimension 30x30x1.6mm3. It produced a triple band of frequencies 4.5GHz, 5.8GHz and 6.8GHz with return loss of -13.81dB, -15.80dB, -11.17dB respectively. With FR4 as dielectric medium having a permittivity of 4.4, a radiation pattern that is stable, gain which is acceptable and impedance matching are noticed at the desired frequencies using the tool HFSS. The intended antenna is compact in nature and offers high gain making it suitable for cognitive radio, wireless local area network and fixed satellite applications.
