摘要：

This article represents a microstrip line-fed novel circular monopole antenna with ultra-wideband (UWB) characteristics. The compact antenna provides reconfigurable notches at WLAN (5.2/5.8 GHz) and Wi-MAX (5.5 GHz) frequency bands. The band rejection is achieved by etching an open-ended L-shaped slot in the ground plane, which effectively mitigates the interference between WLAN, Wi-MAX, and UWB systems with an effective patch area of 36.26%. The proposed antenna operates from 3.05 to 12.11 GHz with VSWR <= 2 except at stopband (3.89-5.93 GHz) to filter the WLAN and Wi-MAX signals. The simulated return loss, gain, and radiation pattern of the proposed antenna has been experimentally verified with the fabricated one which holds a good agreement.
