Original Abstract

The potential ways how to excite optimal currents are discussed in this paper. It is be shown that realistic feeding is not compatible with optimal current distributions and therefore proper shape modifications are needed, changing thus, however, the original optimal currents. A set of deterministic algorithms to synthetize feeding network or the radiators geometry will be summarized, and novel procedure to get suboptimal shapes will be presented. Results will be compared with state-of-the-art multi-criteria algorithms. The paper is concluded with an observation that present understanding of geometry optimization needs to be extended alongside with deeper understanding of influence of the radiator’s shape on its physical behavior.
