Abstract

This article presents an adaptive method for antenna reflection and transmission parameters measurements using a calibrated vector network analyzer without an anechoic chamber. The method is based on a special distance-frequency system model simulating signals of local reflectors. Antenna parameters are extracted from measurement results by using a special estimation algorithm based on the least mean squares method. Experiment was performed and verified the proposed method. Software implemented this method is developed.
