ABSTRACT:
A parametrically amplifying traveling-wave antenna utilizing parametric amplification by strong coupling or resonance between an induced wave and an incident sky wave, the antenna including a base-plate or ground having electrical constants satisfying the resonance condition and a conducting wire or array installed above the base-plate or ground. Both ends of the wire are terminated by a surge impedance to prevent reflections.
