在这篇文章中，它表明，通过互补开口环谐振器实现的超材料传输线是有用的平面微波元件的设计与小尺寸和宽的工作带宽。这些特性的实现得益于互补开口环谐振器的小的电尺寸和在这样的人工线路中的色散图的可控性。该技术是通过一个老鼠赛跑混合耦合器的设计来说明。这种基于超材料的组件的性能和尺寸与经典（分布式）实现的特性和尺寸进行了比较。它清楚地表明，通过取代传统的传输线的设计与超材料传输线方便地设计，设备的功能被保留在更宽的带宽，此外，实现了显着的尺寸减小。这些特性以及在设计中没有集总元件对于其中成本和与全平面技术的兼容性是基本方面的应用是有意义的。本文最重要的贡献是论证了谐振人工线与宽带高性能微波器件设计的兼容性。© 2007 Wiley Periodicals，Inc.

In this article, it is demonstrated that metamaterial transmission lines implemented by means of complementary split rings resonators are useful for the design of planar microwave components with small dimensions and broad operational bandwidths. These characteristics are achieved thanks to the small electrical size of complementary split rings resonators and to the controllability of the dispersion diagram in such artificial lines. The technique is illustrated by means of the design of a rat‐race hybrid coupler. The performance and size of this metamaterial‐based component is compared with those characteristics and dimensions of the classical (distributed) implementation. It is clearly demonstrated that by replacing the conventional transmission lines in the design with metamaterial transmission lines conveniently engineered, the functionality of the device is preserved over broader bandwidths and, additionally, significant size reduction is achieved. These characteristics and the absence of lumped elements in the design are of interest for applications in which cost and compatibility with fully planar technology are fundamental aspects. The most relevant contribution of the article is the demonstration of the compatibility between the resonant artificial lines and the design of broad band and high performance microwave components. © 2007 Wiley Periodicals, Inc.
