There is provided an apparatus for measuring the radiation efficiency of an antenna, the apparatus comprising a chamber, a device under test holder, at least one field stirrer and a measurement device, wherein the holder, field stirrer and measurement device are mounted in line with one another...
Theefficiencyof an antenna relates the power delivered to the antenna and the power radiated or dissipated within the antenna. A high efficiency antenna has most of the power present at the antenna's input radiated away. A low efficiency antenna has most of the power absorbed as losses within ...

PURPOSE:To reduce a difference between receiving levels and measure an antenna efficiency with a high accuracy by arranging metallic wave scattering bodies around a transmitting antenna to be measured or a reference transmitting antenna and arranging a wave shielding curtain between transmitting and receiv...
The time reversal (TR) technique is applied in a reverberation chamber (RC) to perform an analysis of antenna efficiency. RC are mainly used for electromagnetic compatibility measurements. They provide through a stirring process the tota... GL Fur - 《Antennas & Propagation IEEE Transactions on》...
Fundamentals of microwave engineering 1.7.1.5 Efficiency There are other important metrics that evaluate the performance of amplifiers. For example, RF power amplifiers convert a low-power radio-frequency signal into a higher-power signal and typically drive the antenna of a transmitter. One important...
