    Investigation of Normalization Values of S-Parameters in Microstrip Antenna Structure in Pathological Tissue Samples
    (EJOSAT, 2021) Toprak Rabia; Gültekin Seyfettin Sinan; Uzer Dilek
    Studies on the examination of pathological tissue samples with antennas have begun to be developed. In this study, normalization studies performed using a microstrip antenna structure with increased gain are presented. FR-4 substrate with a dielectric constant of 4.4 is preferred in the antenna structure used in the normalization studies. In pathological tissue samples, samples of normal and cancerous skin tissue are modeled in HFSS and simulated. The differences in the normalized S-parameters as a result of the simulations are shown in the tables. While the normal skin tissue normalization value at S11 is 13.4, the value for the tumor skin tissue sample is 18.0. For other S-parameters, different values are obtained for normal and cancerous skin tissue. The differences in the values reveal the success of the proposed antenna structure.
