ABSTRACT
This chapter presents a comprehensive comparison to other popular wideband antenna design approaches that have been developed since 2000’s, in terms of operation principle, closed-form design formulas for initial key parameters estimation, required external accessory, mode gauged functionality, and configuration complexity. As can be concluded, the multi-mode resonant antenna design approach is rigorously based upon the generalized odd-even mode theory. The usable modes can be clearly identified to yield wideband antenna designs with the simplest, basic configuration. In addition, it is compatible to other design approaches when external accessories can be properly incorporated. As is expected, the multi-mode resonant antenna design approach can get wide applications in future antenna engineering.
