Abstract
A system that incorporates the subject disclosure may include, for example, a circuit for measuring from a first probe a first magnitude of radiated energy by an antenna, where the first probe serves as a first near field probe for measuring radiated energy from the antenna, measuring from a second probe a second magnitude of a transmit signal supplied to the antenna, where the second probe is placed at a location for measuring the transmit signal, comparing the first and the second magnitudes to generate a differential magnitude, and providing the differential magnitude to a controller for detecting an offset in an operating frequency of the antenna based on the differential magnitude, and for adjusting the operating frequency of the antenna to mitigate the offset. Other embodiments are disclosed.
