Microwave Imaging: CPW Fed Microstrip Patch Antenna with Defected Ground Plane Operating in ISM Band for Breast Tumor Detection
2022 27th Asia Pacific Conference on Communications (APCC)(2022)
Abstract
A Coplanar Waveguide (CPW) fed patch antenna with defected ground plane operating in microwave range, i.e. license free 5.8 GHz ISM band is presented for breast tumor detection. The antenna offers a size of 50x50x1.2 mm(3) on a Rogers RT5880 substrate material with a loss tangent of tan delta = 0.0009. The optimized antenna can successfully detect the presence of a tumor cell surrounding with healthy tissues in a breast phantom. The reflection coefficients (S-11) of the proposed antenna with and without tumor are -24.11 dB and -23.96 dB respectively. The gain of the designed antenna remains 5.65 dB at 5.8 GHz with tumor cell. The proposed CPW fed microstrip patch antenna operating in license free ISM Band provides us a feasible solution to detect breast tumor successfully through microwave imaging at an early stage.
