Abstract :
An Antipodal Vivaldi Antenna to be used in ultra wideband Medical imaging system is presented in this paper. A new high order power exponential function was used in the design of the proposed antenna, and the measurements showed that the in-band return loss is below -10 dB from 1GHz to12GHz. The experimental result indicates that the antenna is capable of sending and receiving very narrow pulse, which be used in Medical imaging system.
