Antenna parameters measuring by electric field intensity

The antenna is an essential part of a test system. In some applications, selecting the best antenna may be very important. Unfortunately, selecting the right antenna can be a difficult task, because of variation in the way manufacturers specify and describe them. This article explains the specific method of the antenna parameters definition by measurement in an electromagnetic field. Measurement principle and measurement results of the antenna parameters in relative wide frequency band without etalon antennas by using of the electric field intensity are described.
