1. An antenna for use as a power source with a load having a complex impedance comprising:

  • a. an antenna section that has one or more elements and one or more antenna terminals, the antenna tuned to receive a radio frequency signal having a wavelength, an impedance across the antenna terminals having a real and a reactive part; and

    b. one or more loading bars, each loading bar having an effective length, the loading bar being within an antenna distance of at least one of the elements of the antenna over the effective length, the antenna distance being less than one quarter of the wavelength, and the loading bar reducing the real part of the impedance such that power delivered to the load by the antenna is increased.
