Development of standard set for HF electrical field

摘要

This paper describes on the standard set for the HF electrical field, which was completed using "standard electrical field method" recently. The standard transmitting antenna consists of thirteen half-wave tuned dipole antennas, whose operating frequency are different. The frequency range covers from 30 to 1,000 MHz. The transmitting field strength is 100～120 dBμV/m on the steel open area test site with the dimensions of 40m×12.5m. Uncertainty is less than 1 dB. It was used for EMC test such as the metrology of electromagnetic field strength and the calibration of antenna factor.
