چکیده
An L-strip proximity coupled circular micro strip antenna is proposed. The structure is investigated using circuit theoretic approach and simulated using IE3D simulation software. The patch is designed on at hick substrate of thickness 11mm for a center frequency of 8.9GHz and provides ultra wide band operation. The parametric study is carried out for horizon tall length of L-strip deviation of patch, and antenna dimensions and return loss radiation pattern, antenna efficiency, radiation efficiency and gain are obtained. It is observed that the band width of the antenna depends on L-strip feed dimensions along with deviation of patch. An ultra bandwidth of 4.35GHz is achieved with consistent ideate on characteristics.
