Abstract

A novel circularly polarized optically transparent wideband dielectric resonator antenna (DRA) is presented in this work for THz band. The proposed DRA consists of a polyimide substrate incorporating a photonic band gap structure, with a transparent glass dielectric resonator (DR) placed on a slotted patch made of indium tin oxide. The proposed antenna achieves circular polarization and wide impedance bandwidth. Performance evaluation shows a peak gain of 6.5 dBi and a consistent LHCP radiation pattern. The proposed DRA is utilized for cancer detection. The shift in antenna's resonance frequency and reduction in gain of DRA help in detecting malign cells.
