3 terms

The following terms and definitions apply to this specification. 3.1 Antenna antenna Converting the high-frequency current energy sent by the feeder into electromagnetic wave energy and radiating it in a certain direction, or vice versa The device that converts the electromagnetic wave energy radiated from space into a high-frequency current energy into the feeder is a guided wave and a free space wave. A device that converts to each other. 3.2 whip antenna rodantenna Divided into active and passive, generally a certain length (usually about 1m) antenna mast, reflector and The antenna base is configured, and the antenna base includes an impedance conversion and signal processing unit. Usually work in the EMC field At 9 kHz to 30 MHz, it is sometimes called a rod antenna or a rod antenna. 3.3 Antenna effective height antennaeffectiveheight The effective height of the antenna indicates the ability of the antenna to transmit or receive electromagnetic energy. Effective height (he) is a mouth The path-related parameter is defined as the ratio of the induced voltage of the antenna to the incident electric field. 3.4 Antenna coefficient antennafactor The ratio of the measured field strength to the voltage generated by the field at the antenna port. ......
