Nowadays multiband antennas are preferred in wireless communication. Emerging technologies demand compact multiband antennas to support different frequency ranges required for diverse applications. This paper outlines the design of quadband antenna mainly for the UWB frequency range. Accordingly, two compact microstrip structures namely Phi Shape Dual Square ring (PSDSR) and Phi Shape Dual Circular ring (PSDCR) are proposed. The concept begins with designing a primary antenna that involves merging of monopole antenna with the PSDSR structure. The designed dimensions of PSDSR viz. ring perimeter, gap and width are applied directly to the PSDCR antenna without any variation. Anysis HFSS has been used to evaluate the performance of proposed antennas in terms of VSWR, return loss, gain, radiation pattern, and surface current. Simulation results reveal that the two antennas have remarkably similar responses in four different frequency bands. The proposed antennas are fabricated on FR4 substrate and have dimensions of 72x23x1.6mm. It is found that measured and simulated results are in close resemblance with each other. The VSWR values are obtained between 1 and 2 which indicate that these antennas have good impedance matching with the feed line. The designed antennas find variety of applications in technologies such as WiFi, WiMAX, WLAN and 5G wireless systems
