Three Antena Gain Measurement Technique

In the paper we can learn explanation like measured error, antenna axis, correction, function, linear regression, method, mismatch correction, amplitude data, power sensor, position, antenna gain, gain measurements, and effect. This paper presents information such as power, waveguide, adapter, gain, frequency, extrapolation, non linear regression, equation, proximity, measured error terms, measurement procedure, and antenna measurements.

Lots of explanation around setup, antenna sets, reflections, standard gain, gain measurement, gain calibration, mounting brackets, pattern, error, calculation, correction error, antenna, and proposed equation are described inside the paper. Below are excerpted from this paper:

This paper will detail the implementation and results of a gain calculation performed on standard gain horns (SGHs) in the LS and XN microwave bands. The three-antenna method was used to ensure the highest accuracy possible, and extensive efforts were made to minimize the error budget. The measurement was performed in a large anechoic chamber, with the receive and transmit antennas placed 4.6 meters high in opposing corners. The resulting fifteen meters of aperture separation (approximately 10D2/λ for LS band and 15D2/λ for XN band) eliminated all measurable aperture interactions and greatly reduced multipath interference from chamber reflections Rigorous analysis of the error terms proved this method to be both accurate and reliable. Typical values of measured error terms will be presented.

Also, this paper presents more regarding three antenna method, polarization, proximity effect, frequency gain, error budget, linear, gain calculation, antenna method, measurement, technique, multipath, and multipath interference.
