Description
Summary:For MWA applications in the ISM band, the bioimplant single slot coaxial antenna and NiTi ring antenna are designed. The characteristics of the Sucoform_86 / coaxial cable used in the design of the single slot coaxial antenna are given. Simulation and measurement results of return loss, input impedance, gain, VSWR of the designed bioimplant single slot coaxial antenna are examined. Tumor ablation simulation configuration used, SAR (f = 2.45 GHz) (1gr) simulation result, cut plane image of antenna, curve and multilayered tissues (skin, fat, muscle, tumor), obtained along the curve using heat sources of different strengths Length (mm) - Temperature (Kelvin) graph and Length (mm) - Electric Field (V / m) graph obtained along the curve are presented. The electrical properties of NiTi material have been measured and presented. The return loss, electrical field and orientation parameters of the designed NiTi ring antenna were analyzed and CST drawing of NiTi ring antenna, return loss measurement mechanism and measurement result were presented.
