Abstract
A printed planar elliptic patch, juxtaposed with the ground pattern in a single substrate, providing an ultra-wideband impedance bandwidth, is presented. The ultra-wideband property for the proposed antenna is achieved by using a new impedance-matching technique of cutting a notch in the ground pattern opposite the microstrip line. The concavity of the ground pattern serves as an effective means of adjusting the gap between the radiating element and the ground plane. With suitable size of notch chosen, the impedance bandwidth of the proposed antenna can be enhanced. Details of the proposed antenna design and measured results are presented and discussed.
