Low-Profile UWB Probe For Precise Time-Domain Functional Imaging

Abstract

In this paper a Double Ridge Waveguide (DRW) antenna fed by a microstrip line covering a frequency band from 0.5GHz to 2.5GHz is designed, fabricated, and measured, for functional microwave imaging. The proposed DRW antenna is used as the probe element in a collateral multi-static system to detect a cylindrical target located inside a human brain liquid medium. Also an approach for the spatial reconstruction accuracy based on maximum time resolution is presented. Measured and simulated results are conducted and discussed.
