Abstract

The design of a double-ridged horn antenna for medical imaging is presented in this paper. The antenna is immersed in canola oil to reduce its size and to achieve efficient coupling of the electromagnetic energy to the breast tissue. The antenna has wideband performance from 1.5 GHz to 5 GHz (3.5 GHz or 108% of impedance bandwidth), which is suitable for radar-based medical imaging. The double-ridged horn antenna has exponential tapered section for impedance matching. The detail design equations and antenna parameters are presented. The fabricated antenna was tested and compared with simulated results, and excellent agreement has been observed.
