Verification of Antenna Sensor with Commercial Handsets By Applying Radiative Calibration Method
Journal of Electronics and Sensors · 2019
This paper describes an antenna proximity sensor for mobile and applications based on the measured reflection coefficient using a bidirectional coupler. A bidirectional coupler which uses forward and reverse parameters is located between radiated antenna and RFFE (RF Front-End). The measured reflection coefficient proved high chances to act as an antenna sensor. The proposed antenna proximity sensor showed excellent performance and some of the test results with Samsung smartphone are attached to prove it.
