Abstract

Square patch antennas (SPA) are widely used today is in wireless communication systems, mainly with a popular frequency of 2.4 GHz. Wireless devices is the main source of electromagnetic (EM) radiation, which penetrates the tissues of human and causes health danger. In this paper, SPA antenna is designed, simulated and evaluated at 2.4 𝐺𝐻𝑧 for internet application by using CST Microwave studio 2014. Specific absorption rate (SAR) is the term, which measures the exposure of human to EM radiation of communication antenna. SAR values are calculated over 1 𝑔𝑚 𝑎𝑛𝑑 10 𝑔𝑚 mass of tissues, according to the IEEE and International Commission on Non-Ionizing Radiation Protection (ICNIRP) standards for head safety. The SPA antenna produces the smallest SAR levels in adult head tissues. The SAR levels in same tissues are highest in standard (ICNIRP) compare in (IEEE).
