Abstract

Ultra-wideband biomedical radar systems are an important means for the diagnostic inspection and monitoring of physiological signatures. Geometrically small antennas and high-resolution imaging techniques are required for such applications. We have developed compact ceramic double-ridged horn antennas for contact-mode measurements with a permittivity matched to human tissues. In the focus of the present work is the experimental evaluation of the complex permittivity of the ceramic material.
