Abstract
A compact high-sensitivity probe for sensing up tangential E-field is proposed and measured in this paper. The probe consists of an electric dipole with patches used to induce the tangential E-field, a resonator made up of open circuit stubs (capacitor) and short circuit stubs (inductor), for achieving a specific resonance, and a compact coupled balun for transforming the differential-mode voltage into the single-output voltage and impedance matching. The probe is fabricated on five-layer dielectric lamina. Compared with the referenced broadband probe, the measured |S12| of the probe is enhanced by 18.81 dB. The proposed probe in this paper is validated with simulation and measurement.
