Abstract

In this paper a micro-strip Bluetooth low energy (BLE) patch antenna with a copper patch of length 20 mm, width of 14 mm and a 433 MHz antenna with a copper patch of length 85 mm and width of 140.75 mm is used for IOT applications with permitted specific absorption rate (SAR) values. The BLE patch antenna works in the personal area network and the 433 MHz antenna works in the Wide area network. The BLE patch antenna is very useful because of its low data rate, extended sleep periods as this leads to very low consumption of power. Both the antennas used in this paper are simulated keeping in mind the effects of radiation on the human body. So, even though mobile multimedia has many advantages but due to data transmission, heat generated (or heat radiated) from these sensory devices are high and results in heat dissipation. The SAR value obtained for BLE antenna is 0.90337 W/kg and gain is 3.39 dB. The SAR value of 433 MHz antenna is 0.09021 W/kg and gain is 7.66 dB. So, the SAR values were analysed and optimized for the designing of the above stated antennas.
