Abstract : Recent advances in wireless technology have led to the overexposure of living beings to electromagnetic radiation (EMR). The continuous exposure to these EMR creates health hazards for living communities based on the the amount of absorption and its interaction with different parts. It is dependent on the material characteristics of the tissue and the field distribution based on the frequency of exposure. This research work investigates the absorption characteristics of leaves of Tectona grandis (teak). The dielectric properties of the leaves were experimentally measured using the Keysight N1500A-001 solid dielectric probe kit. A microstrip patch antenna (MSA) operating at 2.45 GHz is designed as a source of EMR, and SAR analysis is performed using ANSYS Electronic Desktop 2025. The relationship of the SAR value with respect to the position, thickness, and area of the leaves is observed, and the SAR value of the leaf shows a linear relationship with the surface area. The SAR value ranges from 13.058W/kg to 17.982W/kg and 0.567W/kg to 0.824W/kg when the leaf is placed in the direction of main lobe and back lobe of the antenna respectively.
