Numerical investigation of a new ultra-wideband dual-polarized square horn antenna for pulse radiation and the early-stage breast cancer detection

Microwave imaging via space-time beamformer is one of the new techniques that is used for breast cancer detection. Malignant tumors that are asymmetric or that are not exactly perpendicular to the center of main lobe, are detectable in the cross-polarized backscattered signal. An appropriate antenna is one of the most important parts of this system. This antenna should be small, capable of working in the Ultra-Wideband frequency (1-11GHz) and be able to measure crosspolarized backscattered signal. In this project we design this antenna.
