In this paper, we designed the 3-axis isotropic electric-field measurement probe using resistor-loaded short dipole with lumped chip resistors. The designed probe shows good isotropic characteristics as well as wideband and low sensitivity. The isotropic characteristics of ${\pm}0.39dB$ from 100 kHz to the 3 GHz band were derived and the reception sensitivity was 0.1 V/m. The frequency response is within 3 dB of the whole section, especially ${\pm}1.3dB$ from 150 kHz to 3 GHz, which is superior to the conventional electric field probe with short dipoles.
