Abstract

Electric field measurement plays a significant role in various scientific and technical areas. Here we propose an electric field sensor by using array conical dipole antenna electrodes modulator based on lithium niobate, with 0.12V/m minimum detectable electric field and 82V/m measuring range. The frequency response bandwidth is up to 18GHz.
