Design of an imaging chamber for biomedical applications using bowtie antennas

A microwave imaging system for breast cancers using a miniaturized bowtie patch antenna array is presented in this paper. The antenna element was designed with resonant frequency of 2.57 GHz and return loss less than -15 dB. Thirty-six antennas were installed on the walls of the chamber. The back propagation method is used as the imaging algorithm. We demonstrate the capability of the proposed antenna array for imaging biocompatible immersion medium.
