Summary:
A compact printed antenna with band-notch characteristics for WLAN is proposed. The proposed compact antenna consists of a partial ground plane and an annular ring patch with a partial annular slot. By properly designing the annular slot placed at the lower side of the ring radiator, good frequency rejection of 5.1- 5.9 GHz with a wide operating band from 3 to 10.6 GHz can be obtained. Furthermore, a symmetric radiation pattern and stable gain except in the notched band makes the proposed antenna suitable for being used in UWB applications.
