Dual Slot H Shape Antenna for SAR Estimation

Abstract

In the proposed work, H-shaped microstrip antenna is designed with two slots. Itoperates at a frequency of 2.2GHz with a FR-4 substrate. The proposed antenna is designed for UHF application like mobile communication. The dimension of the proposed antenna is 42 x 30x 1.6 mm^3. Two equal size parasitic patches are being introduced to implement the H shape and simulated using HFSS software. Further, Specific Absorption Rate (SAR) of the proposed antenna is found out. Average SAR value for this proposed design appears to be 0.39 W/Kg, which is also far less than the prescribed value by Telecom Engineering Center (TEC) of 1.6W/Kg.
