本文对紧凑型共面波导(CPW)馈电的零阶谐振(ZOR)天线进行了设计和分析。它们设计在不需要过孔的共面波导单层上。利用ZOR现象减小天线尺寸。在无瓶单层上的新型复合右手/左手(CRLH)单元简化了制造过程。此外，共面波导几何结构提供了很高的设计自由度，因此可以设计带宽扩展的ZOR天线。天线的带宽由电路参数来表征。基于所提出的带宽扩展技术，设计了对称天线、非对称天线和芯片加载天线。通过商用电磁模拟器对ZOR特性和带宽扩展进行了验证。将它们的性能与以前报道的超材料谐振天线进行了比较。它们进一步缩小了尺寸、提高了效率、简化了制造并扩展了带宽。
This paper presents the design and analysis of compact coplanar waveguide (CPW)-fed zeroth-order resonant (ZOR) antennas. They are designed on a CPW single layer where vias are not required. The ZOR phenomenon is employed to reduce the antenna size. The novel composite right/left-handed (CRLH) unit cell on a vialess single layer simplifies the fabrication process. In addition, the CPW geometry provides high design freedom, so that bandwidth-extended ZOR antennas can be designed. The antenna's bandwidth is characterized by the circuit parameters. Based on the proposed bandwidth extension technique, symmetric, asymmetric, and chip-loaded antennas are designed. The ZOR characteristic and bandwidth extension are verified by a commercial EM simulator. Their performances are compared with those of previously reported metamaterial resonant antennas. They provide further size reduction, higher efficiency, easier manufacturing, and extended bandwidth.
