Abstract

Construction of synthetic basis functions (SBFs) for analyzing the radiation problems of antenna arrays is discussed. The SBFs of a block are generated from two separate solution spaces, with one space to account for the effect of the feeding voltages, and the other space to account for the responses of the block to incident electromagnetic fields from its environment. Singular value decomposition (SVD) method is used to extract the characteristic modes of the block. Examples show that using SBFs constructed in this way may cause better efficiency.
