Broadband zero-bias Schottky detector for E-field measurements up to 100 GHz and beyond

Abstract

A broadband detector for electrical field measurements is presented in this paper, deploying an attenuated dipole resonance. High sensitive zero-bias Schottky diodes with anode diameters of 1.5μm allow electrical field characterization down to 1.6 V/m at millimeter wave frequencies. The covered frequency range from 1 to 100 GHz shows a potential voltage response flatness of ±1 dB.
