Abstract

This paper reports the design of a wideband compact microstrip-fed tapered-slot antenna for brain imaging. The antenna is assumed to operate in a coupling liquid that is designed to improve the signal penetration of the imaged object, and thus to increase the dynamic range of the imaging system. The antenna is covered with a dielectric material in order to protect it from the harmful effects of the coupling liquid. The designed antenna operates across the band from 1 GHz to 4 GHz. Its performance is tested in the presence of a multilayer head phantom. The time domain response of the antenna indicates its capability to support distortionless pulse transmission with a high fidelity factor.
