Quasi Yagi-Uda Antenna Array for Detecting Targets in a Dielectric Substrate

摘要

Confocal algorism using microwave propagation is a promising candidate for the early-stage breast cancer detection. In this paper, the dipole antenna and the quasi Yagi-Uda antenna were fabricated on printed circuit boards (PCB) for detecting targets in a dielectric substrate. The Yagi-Uda antenna showed the higher resolution of confocal imaging than the dipole antenna.
