An elliptic-card UWB antenna for wireless communications

An elliptic card UWB planar antenna is designed and miniaturized in this paper. A novel feeding mechanism is proposed to feed the antenna by using a microstrip line on the other side of the substrate and connecting the line to the elliptical element by a via. The structure of the antenna is miniaturized to have minimum length. All antennas characteristics are verified by measurement results. These overall results propose the antenna to be a good candidate for UWB wireless communications.
