Design of CPW Feed Complementary Split Ring Resonators Loaded Microstrip Antenna for Brain Tumor Detection

The CST programme was used to create a novel and compact Microstrip patch antenna with Complementary Split Ring Resonators (CSRR) to identify and see tumours inside the human brain. To represent the head phantom, appropriate tissue parameters such as permittivity and conductivity at the antenna resonant frequency were used. The antenna will broadcast an equivalent signal and receive backscattering signals from the stratified human head model. To improve performance, a complementary Split Ring Resonator with metamaterial structure was created, and a faulty ground structure was incorporated on the antenna ground plane. To investigate antenna performance, rectangular structures are presented. The CRRs were used in the antenna design, together with a defective ground plane structure, to improve return loss, impedance bandwidth, and antenna gain as compared to a patch antenna without split ring resonators. Tumors of various forms and sizes were studied in this study to detect the presence of tumours at an early stage. Various parameters like Electric field intensity(E), magnetic Field Intensity (H), Current density, Power Loss Density are observed, and simulated results compared with and without tumor in the brain.
