通过测量、保角映射和时域有限差分（FDTD）技术确定具有有限宽度接地层的共面波导的最佳接地层宽度。线的衰减和有效介电常数与其几何形状有关。研究发现，如果接地平面宽度大于中心导体宽度的2倍，但小于λ（sub d）/8，则有限接地共面线（FGC）的特性与接地平面宽度无关。此外，电磁场图首次表明，在基板的平面上的电场终止于接地平面的外边缘，并且这些字段的大小与接地平面的宽度有关。
Coplanar waveguide with finite width ground planes is characterized through measurements, conformal mapping, and the Finite Difference Time Domain (FDTD) technique for the purpose of determining the optimum ground plane width. The attenuation and effective permittivity of the lines are related to its geometry. It is found that the characteristics of the Finite Ground Coplanar line (FGC) are not dependent on the ground plane width if it is greater than twice the center conductor width, but less than lambda(sub d)/8. In addition, electromagnetic field plots are presented which show for the first time that electric fields in the plane of the substrate terminate on the outer edge of the ground plane, and that the magnitude of these fields is related to the ground plane width.
