Wearable Microstrip Patch Ultra Wide Band Antenna for Breast Cancer Detection

This paper illustrates a novel design for a wearable microstrip patch ultra-wide band (UWB) antenna with improved bandwidth design to be used in breast cancer detection. The operating frequency of the proposed antenna ranges from 1.6 GHz to 11.2 GHz. The antenna consists of a rectangular radiating patch fed by a rectangular feed line. This antenna design will be part of a wearable device for women to detect breast cancer early. To support wearable property, 100% cotton has been utilized as the substrate with dielectric constant 1.6, while the transmitting component patch and ground planes are composed of copper as the conductive material. The analysis of the antenna and breast models was carried out using CST Microwave Studio. Simulated results in terms of return loss, bandwidth, radiation pattern, and gain and efficiency are presented to validate the usefulness of the proposed design, and different bending conditions are presented.
