Slot-Loaded Pentagon Microstrip Patch Antenna for Hyperthermia Application at 434 MHz

Abstract

In this paper, a slotted pentagon ringtone patch antenna is proposed for the hyperthermia application. The proposed antenna operates in the ISM of 434 MHz and the size of the proposed antenna is 120 × 120 × 1.6 mm3, making it a more suitable applicator for hyperthermia treatment. The antenna structure is considered in the combined single-layer human tissue model and simulated in Ansys HFSS 2020R1 software. The gain obtained for the proposed antenna is − 9.1 dBi. The specific absorption rate is achieved for the x-axis variation inside the phantom at different penetration depths, and these are all within the limits of the IEEE standards. © 2023, Metrology Society of India.
