  "abstract": "This paper presents a plasma-based approach for wideband impedance matching of electrically small antennas (ESAs). By exploiting the negative permittivity of a capacitively coupled plasma (CCP), the plasma is shown to function as a wideband negative capacitor that effectively compensates for the large and frequency-dependent reactance inherent to ESAs. A VHF/UHF electrically small capped dipole antenna is used as a proof-of-concept platform to demonstrate the proposed technique. Theoretical analysis, Multiphysics simulations, and experimental measurements confirm broadband impedance matching, with -6 dB fractional bandwidth that can exceed 100\\%, using only a few watts of plasma power. The matching bandwidth can be dynamically tuned by adjusting the plasma operating conditions, gas pressure, and electron density, enabling control over the trade-off between bandwidth and radiation efficiency. This plasma-enabled matching paradigm provides a physically robust and scalable solution for wideband ESAs, particularly attractive for low-frequency and high-power applications where conventional matching techniques are fundamentally limited.",
