Automated method of antenna factor measuring

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 factor (AF) as one of the main antenna parameters definition by measurement in an electromagnetic field. Automated method of antenna factor measurement (AMAFM) in anechoic chamber is described.
