Abstract
A compact high-sensitivity probe for sensing up tangential E-field is
proposed and measured in this paper. The probe is consisted 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.
