چکیده
In this article, a novel and compact ultra-wideband (UWB) planar antenna is presented. This antenna consists of an annular patch and a 50 microstrip feed line. The 3.5/5.5GHz dual band-notched characteristic gets achieved by etching a C-shaped slot in the patch and complimentary split ring resonator (CSRR) structure in the ground. The measured results show that the proposed antenna can achieve the voltage standing wave ratio (VSWR) requirement of less than 2.0 in very UWB frequency range from 3.05GHz to 23.8GHz with dual band-rejection performance of 3.4 to 4.0GHz and 4.92 to 6.0GHz. Measured VSWR of the proposed antenna is in good agreement with the simulated result.
