ANTENNA STRUCTURES AND METHODS THEREOF FOR DETERMINING A FREQUENCY OFFSET BASED ON A SIGNAL MAGNITUDE MEASUREMENT

摘要

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 is placed near the antenna, obtaining a second magnitude of a signal supplied to the antenna, comparing the first and the second magnitudes, detecting an offset in an operating frequency of the antenna based on a difference between the first and the second magnitudes, and adjusting the operating frequency of the antenna to mitigate the offset in the operating frequency of the antenna. Other embodiments are disclosed.
