Abstract

A miniaturized printed antenna with extended circular patch and partial ground plane for ultra-wideband applications is designed and investigated. The overall structure volume of the antenna is 15 * 20 * 1.6 m3. Proposed antenna’s reflection coefficient (S11 < − 10 dB) is 3.1–20 GHz with the Impedance B/W of 146.3%. The values of the peak gain and antenna efficiency stand at 4.8 dB and 67% respectively, both of which are achieved in the operational frequency band of the design. The suggested antenna with stable far-field pattern satisfies the monopole conditions. The both measured and simulated Co-pol. and (X)-pol. are relatively good agreement. The CST simulator is used to make the proposed structure. The frequency shifted to 3.1 GHz by making a partial ground plane and higher frequency shifted to 20 GHz by introducing a to circular parasitic element is placed in the circular ring slot of the patch. The proposed structure is tested to validate the results of the simulations thus, a good agreement between measured and simulated results is satisfactory that proves the structure’s validity for UWB applications. The proposed antenna finds application in WiMAX-band of 3.5, 5.5 GHz, WLAN-band of 5.2, 5.8 GHz, X-band of 8–12 GHz.
