A broadband antenna using the modified ground plane with a complementary split ring resonator for 5‐GHz WLAN band‐notched performance

In this article, a new configuration of a broadband antenna is proposed.The designed antenna is an elliptical monopole antenna with a complementary split ring resonator structure that is inserted in the ground plane for rejecting the 5-GHz WLAN band (5.15–5.35 and 5.725–5.825 GHz). In addition, impedance matching technique implemented by rectangular slot applied to the ground plane is suggested. The technique can be an effective method to achieve the wider bandwidth. The designed antenna shows that a VSWR less than 2 was satisfied with a resonant frequency in the range of 2.67–12 GHz. © 2011 Wiley Periodicals, Inc.
