Abstract

The design and characterization of a printed semi elliptic slot antenna with wide impedance bandwidth is presented in this paper. The antenna comprises of a semi-elliptic patch and a modified ground which is designed to give an impedance bandwidth from 2.85--20 GHz for S11 less than -10dB. The structure is more compact compared to other slot antennas having the same electrical characteristics. Experiments indicate omnidirectional radiation with appreciable gain throughout the Ultra Wide Band (UWB) 3.1--10.6 GHz. Empirical relations for the resonances in the antenna is also presented in this paper. Transient analysis indicates good pulse handling capabilities.
