Abstract
- A novel procedure based on characteristic modes (CM) and differential evolution (DE) algorithm is proposed for electrically loaded Yagi-Uda antenna synthesis. In this method, optimal Yagi- Uda antenna designs are realized by electrically loading, other than by tuning the sensitive physical dimensions. The traditional fullwave analysis in objective function evaluations is replaced by a simple summation of the CM, thus the optimization efficiency is greatly improved up to 4 orders. Antenna performances are compared to published results to illustrate the effectiveness of the present method. [ABSTRACT FROM PUBLISHER]
