摘要:
A method and apparatus for providing close proximity antenna measurement and tuning, includes a first receive-only antenna, a second antenna operable in a transmit mode, a tuning circuit coupled to the first antenna, a transmitter coupled to the second antenna, a receiver coupled to the first antenna, the receiver operable to measure a power into the first antenna delivered by a signal from the second antenna driven by the transmitter, and a processor coupled to the tuning circuit, transmitter, and receiver, the processor operable to step changes in the tuning circuit until a substantially maximum power of the signal is measured by the receiver.
