Abstract: A method and an apparatus are provided in which a first signal is received at a bi-directional coupler of an antenna path. A first power, delivered to an antenna of the antenna path, is measured based on a second signal corresponding to a forward signal provided from the bi-directional coupler to the antenna and a third signal corresponding to a reverse signal reflected back to the bi-directional coupler from the antenna. A power correction value is determined based on a ratio of the second signal to the third signal and a one-to-one relationship of the ratio to a load reflection coefficient of the antenna. A second power delivered to the antenna is determined based on the first power and the power correction value.
