摘要

这项工作解释了双频双极化超材料(MTM)天线的设计和开发，该天线结合了人工磁导体(AMC)地平面，具有更高的增益和圆极化(CP)特性。天线结构紧凑主要是由于左/右复合传输线采用零阶谐振(ZOR)模式和AMC接地面的应用。预期MTM天线的电尺寸为0.19 $\boldsymbol{\lambda}_{0}\乘以0.23\ \boldsymbol{\lambda}_{0}\乘以0.012\ \boldsymbol{\lambda}_{0}$在2.38 GHz ($\boldsymbol{k}\boldsymbol{a}=0.97 < 1$)。AMC地平面MTM天线在2.35 GHz和5.5 GHz为中心的第一频段和第二频段的带宽分别为11.46%和26.18%。天线在第二波段显示CP辐射，轴比带宽(ARBW)为3.80%。该天线为两个频段提供了6.15 dBi和6.96 dBi的更高增益。该天线具有更高的增益、良好的辐射效率、更宽的带宽和更小的尺寸。该天线适用于4G-LTE、WLAN和WiMAX应用系统。

A Compact Dual-Band and Dual-Polarized Open-Ended ZOR Antenna with AMC Ground Plane for 4G-LTE/WLAN/WiMAX Applications

This work explains the design and development of a dual-band and dual-polarized metamaterial (MTM) antenna incorporating artificial magnetic conductor (AMC) ground plane for higher gain and circular polarization (CP) characteristics. Antenna compactness is due to the zeroth order resonance (ZOR) mode of composite right/left-handed (CRLH) transmission line (TL) and the application of AMC ground plane. The electrical size of the intended MTM antenna is 0.19 $\boldsymbol{\lambda}_{0}\times 0.23\ \boldsymbol{\lambda}_{0}\times 0.012\ \boldsymbol{\lambda}_{0}$ at 2.38 GHz ($\boldsymbol{k}\boldsymbol{a}=0.97 < 1$). The MTM antenna with AMC ground plane provides a bandwidth of 11.46% and 26.18% for the first and second frequency bands centered at 2.35 and 5.5 GHz. The antenna shows CP radiation in the second band with an axial ratio bandwidth (ARBW) of 3.80%. The antenna provides a higher gain of 6.15 dBi and 6.96 dBi for both the bands. The antenna provides higher gain, good radiation efficiency, wider bandwidth, and compact size. The antenna can be suitable for working in 4G-LTE, WLAN, and WiMAX application systems.
