摘　　要：设计了一种新型的基于非对称共面波导(ACPW)馈电复合左右手传输线(CLRH-TL)的四频段混合小型化天线。天线由非对称共面波导接地面加载互补开口谐振环缝隙、单极子天线终端加载复合左右手传输线单元组成,将常规单极子天线与超材料结构的零阶谐振器天线双模式混合。实测结果表明:天线回波损耗大于10 dB的阻抗带宽分别为1.55~1.65 GHz,2.4~3.7 GHz,5.15~5.36 GHz,5.71~5.89 GHz,通带内具有良好的辐射特性。天线结构简单紧凑,易于集成,可应用于GPS,WLAN和WiMAX无线通信系统中。A novel quad-band hybrid miniaturized antenna based on Asymmetric Coplanar Waveguide(ACPW)feeders Composite Left and Right Hand Transmission Line(CLRH-TL)is proposed.The antenna is composed of ACPW connected with ground loading open resonant ring gap and monopole antenna terminal loading CLRH-TL unit.The conventional monopole antenna is mixed with the metamaterial zero-order resonator antenna.The measured results show that the impedance bandwidths of the antenna with the antenna return loss above 10 dB are 1.55~1.65 GHz,2.4~3.7 GHz,5.15~5.36 GHz and 5.71~5.89 GHz respectively,which have good radiation characteristics in the passbands.The antenna structure is simple,compact and easy to integrate.It can be used in GPS,WLAN and WiMAX wireless communication systems.
