Various embodiments utilize part of an existing antenna pattern in a computing device to implement a specific absorption rate (SAR) sensor element using a radio frequency (RF) filter circuit. The integrated solutions of the present disclosure help to eliminate the external SAR sensor pad requirement and further help to improve wireless performance. The embodiments of the present disclosure may be implemented with a variety of different types of antenna (e.g., slot, metal ring/aperture, PCB, etc.). Other embodiments may be described and claimed.
