With the progress of technologies though the years, the extent of electromagnetic radiations has increased in our environment, so there are increased concerns about health for wireless device users. It has become a necessity to use devices with low Specific Absorption Rate (SAR) to reduce human exposure to the effects of Electromagnetic Fields (EM fields). In this article, the design of a circular microstrip antenna (CMSA) with and without an electromagnetic band gap (EBG) structure is proposed. It is evident from simulated results that CMSA with EBG gives low SAR as compared to CMSA without EBG for the proposed prototype. M-shaped unit cell structure of EBG is designed for 1812 MHz resonance frequency, and a bandwidth of 244 MHz is achieved using CMSA with EBG for LTE Band 3. SAR is reduced by 76.25% when CMSA is used with EBG in comparison to CMSA without EBG.
