Method for antenna measurements by means of the complex reflection factors of the object being measured

摘要

In making antenna measurements for determining the direction of pattern of the occupancy of the near and far field and the gain and efficiency, transmission-type measuring methods have hitherto been used. According to the invention, reflection measuring methods are proposed for this. The object being measured, the antenna to be measured, is not connected to transmitter or receiver but, with defined passive terminations, is measured geometrically three-dimensionally as reflection object via the complex scattering matrix of the reflection factor. To determine the gain by measurements and for calibration, reflection standards such as, for example, spheres or corner reflectors or planar reflectors are used.
