Abstract: A system and method for detecting the presence and performance status of an antenna within a wireless telecommunications device, comprising monitoring a radio frequency (RF) power flow inside the wireless device using a directional coupler to measure both forward RF power originating from the device towards the antenna and reflected RF power originating from the antenna or other discontinuity and reflected back into the device, measuring a return loss based on a discrepancy between the forward RF power and the reflected RF power, comparing the return loss with one or more predetermined threshold values, and determining if the antenna is performing optimally or sub- optimally based on the comparison.
