提出了一种新型的多频带单向辐射贴片天线，通过在设计中集成谐振器。基于耦合谐振器网络实现多个频带。拓扑结构和设计方法进行了详细说明。贴片不仅作为网络的最后一阶谐振器，而且作为辐射元件。使用这种方法，可以在不改变辐射元件的形状的情况下实现多个频带。另外，可以通过调节谐振器之间的耦合来调节操作频带。在这项工作中，四个频段被设计为4.6，5.05，5.8和6.3 GHz作为概念验证。制作了样机并进行了测试，测试结果与仿真结果吻合较好，在阻抗匹配、辐射方向图、增益和交叉极化鉴别等方面表现出良好的性能。
A novel multiband patch antenna with unidirectional radiation is proposed by integrating resonators in the design. The multiple frequency bands are achieved based on a coupled resonators network. The topology and design methodology are detailed. The patch not only works as the last-order resonator of the network, but also as the radiating element. Using this approach, multiple bands can be achieved without changing the shape of the radiation element. In addition, the operation bands can be adjusted by adjusting the coupling between the resonators. In this work, the four bands are designed at 4.6, 5.05, 5.8, and 6.3 GHz as a proof-of-concept. The prototype is fabricated and tested, and measured results agree very well with the simulations, showing an excellent performance in terms of impedance matching, radiation patterns, gains, and cross-polarization discrimination.
