Abstract

In certain antenna arrays (“switched‐element” arrays), some of the radiating elements are turned on or off during operation to provide some desired reconfigurability at different times, or are effectively turned on or off at different frequencies, through the use of filters connected to groups of radiating elements, in order to retain the same performance over wide‐frequency bands. In such circumstances, the excitations of the elements must be the same, irrespective of whether all or only some of the elements are being used. Thus, one may wish to synthesize an array (that is, determine its element excitations) so that the required performance is obtained under different sets of circumstances. In this paper, we indicate how the use of a parallel approach allows the method of generalized projections to be used for such synthesis problems, and demonstrate its use for a specific example. © 2004 Wiley Periodicals, Inc.
