Amplifier providing power recovery from a narrow-band antenna

摘要

A method, amplifier and system are provided for enabling power recover from a narrow-band antenna when a signal have bandwidth exceeding that of the antenna is utilized. The amplifier provides amplification of a source signal to the antenna and power recover of power stored in the antenna during periods when the impedance of the antenna is negative by enable reverse current through the amplifier to a direct current (DC) power source.
