A Miniaturized Patch Antenna with Pins for Breast Tumor Noninvasive Focused Microwave Therapy

This paper presents a miniaturized patch antenna with pins specifically designed for breast tumor noninvasive focused microwave therapy (FMT). There are 32 antennas utilized to constitute an antenna array focusing electromagnetic energy in tumor location while keeping healthy tissue at a safe temperature. The coupling of antennas causes focusing deviation. The miniaturized antenna can increase the distance between elements in order to decline to couple between antennas. Moreover, the offset distance between the focusing point and tumor location can be reduced. Loading pins achieve a lower resonance frequency with a smaller antenna size. The proposed approach utilizing an antenna was applied for the model treating breast cancer.
