提出一种新型PBG-CPW传输线，并对其有效介电常数、相速、特性阻抗等基本特性进行了研究。该结构由多段CPW和PS CPW首尾相接而成，相比传统CPW具有更高灵活性。PBG-CPW具有禁带特性，但在一定条件下可等效为均匀传输线，本文采用传输线模型分析了该传输线的色散特性，给出了简化电路模型，并在此基础上讨论了具有单侧 PBG的非对称PBG-CPW结构的特性和应用，从而对所提出模型进行验证。

A novel PBG-CPW (Photonic Band Gap-Coplanar Waveguide)transmission line is proposed.It is composed of many CPW and PS CPW (Partial Substrate Coplanar Waveguide)stubs,which joined together end to end.Effective dielectric constant,phase ve-locity and characteristic impedance of the PBG-CPW are analyzed with theoretical method. Proposed structure exhibits better design flexibility and photonic band-gap characters.Under certain conditions,PBG-CPW can be regarded as uniform transmission line.Dispersion char-acter of the proposed structure is analyzed with transmission line method while the simplified circuit model is given.Characters of asymmetric PBG-CPW structure and its applications are discussed,which is also used to verify the proposed model.
