报道了一种基于超材料的多频段加载微带天线的设计与分析。所提出的天线由多个谐振器的灵感来自半模复合右/左手单元，它具有简单的结构，紧凑的尺寸，并提供多频带功能。作为概念验证，已经设计、制造和表征了覆盖所有可能的WiMAX工作频带的三频带天线。托管贴片本身产生3.3-3.8 GHz频段的谐振，而加载的超材料单元增加了额外的谐振频率。两个谐振器单元的加载分别为2.5-2.7 GHz和5.3-5.9 GHz频带引入了两个额外的谐振。文中给出了该天线的工作原理和设计步骤，并进行了电磁全波仿真和实验测量。该天线在所有三个频段都具有良好的全向方向图。贴片尺寸为13.5 x 6.5 mm（2），整个天线尺寸（包括馈线）为35 x 32 mm（2）。与传统的单频段微带贴片辐射器相比，该天线的辐射器尺寸在2.5GHz时仅为8.5%，在3.5GHz时仅为17%，在5.5GHz时仅为37%。
The design and analysis of meta-material inspired loaded monopole antenna for multiband operation are reported. The proposed antenna consists of multi resonators inspired from half mode composite right/left handed cells, which has a simple structure, compact size, and provides multiband functionalities. As a proof of concept, a triple band antenna covering all possible WiMAX operating bands, has been designed, fabricated, and characterized. The hosting monopole patch itself generates resonance for 3.3-3.8 GHz band, whereas the loaded metamaterial cells add extra resonance frequencies. The loading of two resonator cells introduces two extra resonances for 2.5-2.7 GHz and 5.3-5.9 GHz bands, respectively. The antenna's operating principle and design procedures with the aid of electromagnetic full wave simulation and experimental measurements are presented. The antenna has good omnidirectional patterns at all three bands. The monopole patch size is 13.5 x 6.5 mm(2) and the whole antenna size (including the feed line) is 35 x 32 mm(2). Compared with conventional single band microstrip patch radiator, the radiator size of this antenna is only 8.5% at 2.5 GHz, 17% at 3.5 GHz, and 37% at 5.5 GHz.
