1. A method of determining an indication of return loss of an antenna of a wireless communication system, comprising:

  • measuring, across a frequency band, at least powers of a signal received at communication equipment from an antenna connected to the communication equipment, the received signal including a leakage signal and a reflected signal, the reflected signal being a reflected portion of a test signal injected into a coupler towards the antenna, and the leakage signal being a portion of the test signal leaking from the coupler away from the antenna to the communication equipment;

    first determining maximum and minimum powers of the received signal based on output of the measuring step; and

    second determining at least an indication of return loss of the antenna based on the determined maximum and minimum powers.
