The Design of the cross semi-elliptic disc monopole antenna and the band-rejected cross semi-elliptic monopole antenna for UWB Applications

Abstract

The cross semi-elliptic monopole antenna and band-rejected cross semi-elliptic monopole antenna with finite ground plane have been implemented and investigated, respectively. Experimental results show that the obtained impedance bandwidths of the two designs of antenna fit the requirement of the UWB applications. The dipole-like radiation patterns over the operating bandwidth are also shown in this paper. In addition, the proposed antenna also shows a compact size, compared to a corresponding elliptic monopole antenna. The proposed design of this antenna with finite ground is suitable for practical UWB applications
