Abstract

This article presents a design of spiral PIFA antenna in MICS band (402 - 405 MHz) for detecting the oral cancer. The antenna is fabricated on the Roger4350 substrate material which has a thickness of 1.524 mm and a relative permittivity of εr = 3.66 with overall dimension of 33.8 x 33.8 mm. The mouth is modeled according to the CST Voxel Katja model and the electrical properties of individual tissues. A human mouth model and the antenna are simulated using CST software. Testing on the face is done in three locations, left and right cheeks and under the chin. Testing on malignant tumors is only simulated on the CST. There is a noticeable resonance frequency shift of the return-loss when the malignant tissues are considered. There is a good matching between the measured and simulated results.
