Abstract
A system includes a radio frequency (RF) connector terminal that is configured to connect to an antenna, and a RF transmitter that transmits RF power to the RF connector terminal. The system further includes a power measurement unit that measures, as a first power measurement, first RF power of the RF transmitter power that is reflected via the RF connector terminal, and a controller that causes a transmission path discontinuity between the RF transmitter and the RF connector terminal. The power measurement unit further measures, as a second power measurement, second RF power of the RF transmitter power that is reflected from the discontinuity. The controller further determines if a first antenna is connected to the RF connector terminal based on the first and second power measurements.
