  • AMPLIFIER PROVIDING POWER RECOVERY FROM A NARROW-BAND ANTENNA
    Publication number: 20120161863
    Abstract: A method, amplifier and system are provided for enabling power recovery from a narrow-band antenna when a signal having bandwidth exceeding that of the antenna is utilized. The amplifier provides amplification of a source signal to the antenna and recovery of power stored in the antenna during periods when the impedance of the antenna is negative to enable reverse current through the amplifier to a direct current (DC) power source.
    Type: Application
