T- and X-arrangement of 'Dark Eyes' Antennas for Microwave Sensing Array

摘要

Ultrawideband radar imaging techniques are currently being studied as a promising tool for breast cancer detection [1]. For this application, several antennas have been suggested [2], [3], however, most of these antennas are designed to sense the co-polarized reflections from potentially existing tumors within the breast. Further improvement of microwave breast cancer detection systems by sensing the cross-polarized reflections was suggested in [4]. In addition, antenna with two bow-tie radiating elements was presented in [2] for polarimetric radar-based imaging. In this paper, we are proposing two different arrangements of the "Dark Eyes" antenna for sensing the cross-polarized reflections from the breast. The antenna is planar, compact and the arrangements can be used to form a cross-polarized antenna array.
