Characterization of Antenna Interaction with Scatterers by Means of Equivalent Currents
By
Progress In Electromagnetics Research, Vol. 116, 185-202, 2011
Abstract
Antenna characterization in presence of obstacles requires removing multipath effects in order to retrieve the nondistorted antenna radiation pattern. In this contribution a new approach based on the Sources Reconstruction Method is proposed. The idea is to characterize the Antenna-Under-Test (AUT) and the region where the scatterers are located through a set of equivalent currents. Finally, the reconstructed equivalent currents on the contour enclosing the AUT can be used to recover the AUT radiation pattern, removing most of the distortion effect due to the presence of the scatterers.
