Here in this article we will see the different methods by which the gain of antenna can be determined. Skip to content. in high-frequency antennas, the losses are considered to be negligible thereby possessing 100% efficiency. Antenna measurement techniques refers to the testing of antennas to ensure that the antenna meets specifications or simply to characterize it. Typical parameters of antennas are gain, radiation pattern, beamwidth, polarization, and impedance. This report of activities explains the measurement technique used to characterize fractal antennas in terms of radiation efficiency and quality factor. First measurements of radiation efficiency and quality factor of prefractal structures are also presented.

The simplest type of VNA is a 1-port VNA, which is able to measure the impedance of an antenna [which is equivalent to measuring S11 and VSWR].More of this will be discussed in the impedance section. Measuring of an antenna's radiation pattern, gain and efficiency AnTune antenna impedance matching and antenna efficiency measurement demonstration. If playback doesn't begin shortly, try restarting your device. Videos you watch may be added to the TV's watch The antenna accepts a certain amount of energy delivered to it by the transmission line (characterized by S11, VSWR, or return loss), and Antenna Efficiency characterizes the amount of energy lost ‘in’ the antenna after this. It is often expressed in terms of a percentage, or in dB. For example, an efficiency of 0.8 is 80%, or -0.97dB.

The second article (see page 34) presents the theory and equations governing antenna properties and includes a complete description of a site calibra-tion for pattern-measurement testing.

The Wheeler cap method is often used to measure the radiation efficiency of small antennas. However, it is well applicable for antennas on a ground plane, but not for balanced antennas like loops or dipoles.
