Abstract

This article presents circular ring loaded multiband antenna with notch band characteristics for wireless communication applications. The antenna is in compact structure with dimensions of 21 x 28 x 1.6 mm3 and designed on the FR4 substrate. Basically, the antenna provides the wide band characteristics and showing multiple notches. To attain the notch band characteristics, the antenna is loaded with two circular ring strips and four inverted C-shaped parasitic elements are embedded on either side of the feed line. The antenna provides maximum peak gain of 4.04 dB with efficiency of more than 78%. The proposed antenna providing notch band characteristics and showing the bidirectional and omni directional radiation patterns in E and H-Planes.
