Abstract

This paper presents the design of an H-shaped microstrip patch antenna to evaluate the SAR (Specific Absorption Rate) for thyroid gland cancer cell detection. This antenna is flexible and appropriate for wearable applications. The performance can be varied when the antenna is placed on the thyroid gland of humans. The parameters like return loss, gain, VSWR are measured. There are different varieties of the antenna but microstrip patch antenna provides low cost, low volume, lightweight etc. FR-4 (lossy) is used as a substrate to overcome low gain and high return loss. The patch conductor is made up of copper material to form a flexible antenna. The proposed antenna design provides a high SAR value of 0.0199W/Kg for 1g of tissue with a tumor. Since cancer cells contain more water content the performance of various parameters can be changed in the proposed antenna design. The gain value of the proposed antenna is 6.36 dB at 16.452GHz. The thyroid gland model of proposed H-shaped and Hshaped vertical slot antennas are designed using CST (Computer Simulation Technology) microwave studio tool.
