Development of standard set for HF electrical field

This paper describes the standard set for the HF electrical field, which was completed using the "standard electrical field method". The standard transmitting antenna consists of thirteen half-wave tuned dipole antennas, whose operating frequencies are different. The frequency range covers from 30 to 1000MHz. The transmitting field strength is 100-120 dBμV/m on the steel open area test site with dimensions of 40 m × 1.5 m. Uncertainty is less than 1dB. It was used for EMC test such as the metrology of electromagnetic field strength and the calibration of antenna factor.
