A novel mobile phone antenna for effectively reducing specific absorption rate

In this paper, a novel mobile phone antenna that can effectively reduce the harm of electromagnetic radiation to the human body is proposed. An inverted F-shaped antenna (IFA) is designed to reduce specific absorption rate (SAR) and all the measurements are done in over the air (OTA) test system. Measured results show that the proposed mobile phone antenna has excellent electrical characteristics such as reflection coefficient (700–870 MHz and 1710–2450 MHz), radiation pattern, total radiation power (TRP >17.5 dBm), hot spot map and low SAR values (< 1.4 W/kg). Due to these advantages, the proposed antenna is used to reduce SAR in the future mobile phone.
