Miniature body-matched double-ridged horn antennas for biomedical UWB imaging

Ultra-wideband imaging has widely proven its potential for biomedical diagnostics. Especially for imaging applications, the miniaturisation of the antennas plays a key role due to the necessity to arrange a high number of sensors around the target under investigation. We have investigated and exploited the potential of dielectrically scaled antennas, designing and manufacturing compact ceramic double-ridged horn antennas. The manufacturing procedure as well as recently measured results are presented.
