摘要：

In this paper, size reduction of antenna structures taking reflection response and total efficiency into account has been investigated. In order to find available design trade-offs concerning the antenna footprint, its wideband matching, and efficiency, numerical optimization has been employed. Appropriate formulation of the objective function permits identification of the designs that exhibit the minimum possible footprint while maintaining the maximum in-band reflection and average efficiency within the prescribed thresholds. For the sake of demonstration, a specific case study of a UWB monopole is considered. A set of designs generated using the proposed approach provides a designer with a comprehensive knowledge about the capabilities of a given antenna topology and facilitates a decision making process driven by a particular application and performance requirements.
