Abstract

Malignant Tumor detection in the body at an early stage can eliminate deaths due to cancer. Wearable devices with antennas working in the range of 6-10GHz can help detect cancer early. A rectangular dielectric resonator antenna (RDRA) with orthogonal feed for circular polarization is presented for tumor detection with a resonant frequency of 6.5GHz and 9.5 GHz. The proposed RDRA with gain up to 5.1dBifor 6.5GHz, 70% axial ratio bandwidth, and 36% impedance bandwidth is obtained. A simple design with considerable broad bandwidth circularly polarized and a good gain solution for 6-10 GHz tumor sensing application is presented with a radiation efficiency of 95%.
