Abstract
The public's growing awareness of the negative impacts of high-volume temperature fluctuations has led to a
marked rise in the Specific Absorption Rate (SAR). In existing techniques, the SAR value is high and more
expensive. To overcome this issue, an Amended Planar Inverted F-antenna (PIFA) with Ferrite Sheet
Attachment for SAR Reduction in Human Head has been introduced to reduce SAR value. The antenna
receives power from the grounded end and Simulated Magnetic Rods (SMR) are utilized in the antenna to
lower SAR values. The PIFA and SMR face major difficulties due to their low reliability and bandwidth.
Hence, Radiating Blotch is implemented within the antenna to increase bandwidth and dependability. The SAR
reduction is increased and various parameters are produced when the header model is simulated using ANSYS
HFSS. Overall, the performance with and without a ferrite sheet comparing the analysis for SAR reduction
with various parameters.
