提出一种具有部分介质的新型共面波导传输线,并采用电磁数值方法对该传输线的有效介电常数、特性阻抗及群时延特性进行分析和仿真.结果表明,该传输线较传统共面波导更为灵活,更加便于调整,同时具有良好的色散特性,有较高的应用潜力和研究价值.
The paper proposed a novel partial substrate coplanar waveguide(PS CPW),and analyzed its effective dielectric constant,characteristic impedance and group delay characters via numerical computations and simulations.Results show that the proposed transmission line has superior flexibility comparing with traditional CPW,and is more easy to be adjusted,while has a good dispersion character.High application potential and research value can be expected for this transmission line.
