Design of a Nove1 100MHz-60GHz Isotropic Electric-Field Probe

A novel 100MHz ~ 60GHz wideband isotropic electric field (E-field) probe, capable of accurately measuring the strength of the electromagnetic radiation, is presented in this paper. The E-field probe mainly consists of tapered resistive dipole and a low-barrier, beam-lead Schottky detector diode. The E-field probe has the ability of measuring 0.7V/m ~ 400V/m. The frequency response of the probe is within ±3dB(300MHz ~ 40GHz). The isotropic response with respect to angle, guaranteed by spatial mutually orthogonal dipole configuration, is within ±1dB.
