Low Profile Microstrip Patch Antennas for Wearable Medical Imaging Application

Abstract

Wearable medical imaging applications are obtaining their importance in the present scenario. These devices need to be low profile with very good efficiency and low SAR. Among the various available antennas, the most efficient and commonly used antenna is the microstrip patch antenna. The proposed inset feed microstrip patch antenna is designed for terahertz frequency and is optimized for the frequency of operation. The antenna’s final dimensions are 0. 62lambda0x0.72lambda0x0.06 lambda0. The low-profile antenna has a return loss of -24dB and a gain of 7dB. The antenna is simulated on a flexible polyimide substrate, allowing it to be used in wearable applications
