Suppression of multipath signals in the indoor antenna radiation measurement using an effective signal process algorithm

This paper summarizes the multipath suppression within an anechoic chamber for the measurement of antenna radiation patterns. The technique employed Matrix Pencil (MP) to characterize the chamber environment in terms of multi-paths, which are stored in memory. The correct pattern of antenna under test (AUT) can be retrieved by calibrating the measured data with the characterization factors. Experimental example will be present to demonstrate the feasibility.
