About the measurement inaccuracies of dispersion diagrams in Fresnel zone



The measurement inaccuracies of dispersion diagrams of an arbitrary body in Fresnel zone that arise because of the finite distance between the body and the radiating antenna, and the body and the receiving antenna, as well as the directivity of the antennas are considered. The measurement inaccuracies of dispersion diagrams in the near zone of collimator in case when the boundary wave effect can be ignored are studied....

Restoring the antenna directional diagram using the Fresnel zone measurements on a measurement stand in a far zone



The method of determining the antenna directional diagram using the amplitude and phase measurements in the Fresnel zone is considered; the mathematical rationale of the method is given along with the results of computer and experimental modeling and the samples of using when measuring the high aperture antennas in an anechoic room with a 80 m route on a measurement ...
