提出了一种基于非对称共面波导（ACPW）的宽带零阶谐振（ZOR）天线。通过采用ε负传输线（ENG-TL），可以实现零阶谐振模式。我们采用非对称共面波导结构，为实现宽带 ZOR 天线提供了设计自由度，其中天线的带宽由等效电路参数来表征。该天线具有紧凑的单元尺寸为5 £ 13:8mm 2 。实测结果表明，工作带宽约为1050MHz(1.90{2.95GHz)，零阶2.3GHz下峰值增益和辐射效率分别为2.46dBi和91%。由于具有宽带宽、高效率、全向辐射和易于制造的特点，所提出的ACPW ZOR天线非常适合现代无线通信系统（UMTS、WLAN、WIMAX、LTE）。
A broadband zeroth-order resonant (ZOR) antenna based on asymmetric coplanar waveguide (ACPW) is presented. By adopting the epsilon negative transmission line (ENG-TL), a zeroth-order resonance mode can be achieved. We employ an asymmetric coplanar waveguide structure which ofiers the design freedom to realize the broadband ZOR antenna, where the antenna's bandwidth is characterized by the equivalent circuit parameters. The antenna has the compact unit cell dimensions of 5 £ 13:8mm 2 . The measured results show that the operating bandwidth is about 1050MHz (1.90{ 2.95GHz), and the peak gain and radiation e-ciency are 2.46dBi and 91% at zeroth-order 2.3GHz. Owing to the characteristics of broad bandwidth, high e-ciency, omnidirectional radiation, and easy manufacturing, the proposed ACPW ZOR antenna is very suitable for modern wireless communication systems (UMTS, WLAN, WIMAX, LTE).
