Abstract

Electrically small electric and magnetic antennas augmented with non-Foster elements to enhance their impedance bandwidths have been designed, characterized numerically, fabricated and tested. Internal non-Foster elements, which produce broad bandwidth inductive and capacitive responses specifically tailored to design specifications, are introduced into the near-field resonant parasitic (NFRP) components of their narrow bandwidth counter-parts. This internal non-Foster element approach leads to nearly complete matching of the entire system to a 50 ω source without any matching network and high radiation efficiencies over their FBW10dB bandwidths that surpass the fundamental passive bounds.
