摘要：
A novel design of a circular patch antenna having Z-shaped defected ground structure is presented in this communication. The antenna is designed for X-band applications. A wideband is obtained in the X-band frequency range 8-12 GHz. The return loss and input impedance is measured experimentally and compared with the simulated results. Parameters like impedance bandwidth, voltage standing wave ratio, and antenna gain are calculated and discussed. Impedance bandwidth of about 1.2 GHz is obtained with a gain of 8.7 dBi and side lobe level of -20.1 dB. (C) 2013 Wiley Periodicals, Inc.
