线状微带传输线类似于标准微带传输线，但使用的是圆形导体。建模近似可用于了解线状微带传输线的阻抗。

The wire microstrip transmission line is similar to a standard microstrip transmission line, but with a round conductor. Modeling approximation can be used to understand the impedance of the wire microstrip transmission line.

微带线由悬挂在接地平面上的圆形导体构成。导体和接地层用电介质隔开。与标准微带走线一样，计算有效介电常数是因为空气位于走线的一侧，而另一电介质位于导线和接地层之间。

A wire microstrip is constructed with a round conductor suspended over a ground plane. The conductor and ground plane are separated with a dielectric. As with the standard microstrip trace, an effective dielectric constant is calculated because air is on one side of the trace where another dielectric is between the wire and the ground plane.

Example

微带线的一个例子最常见于原型或返工板上，其中在 pcb 或覆铜材料的顶部使用导线。如果电线周围有绝缘体，那么这个计算器将是一个估计值。在高度计算中包括 pcb 电介质厚度和导线绝缘层。An example of a wire microstrip might most often be found in prototypes or reworked boards where a wire is used over the top of pcb or copper clad material. If there is an insulator around the wire then this calculator will be an estimate. Include both the pcb dielectric thickness as well as the wire insulation in the height calculation.
