Abstract A phased‐array antenna with switched‐beam elements used to combat interference in an indoor wireless communication system is described. The array uses 1‐bit phase shifters applied to its elements in order to point its main beam in a desired direction and internal switching of elements in order to form nulls towards interference. The array's capability of suppressing interference is verified by studying its radiation patterns and by performing interference‐rejection experiments in an indoor multipath environment. © 2005 Wiley Periodicals, Inc.
