You always have two major ways to loose signal, which are conductor and
dielectric in PCB and coax. Either type of loss can dominate depending
on materials and construction.

Series, shunt?

That's the wrong way to look at it. Coax cable and a micro-strip-line on
a PCB are examples of transmission lines.

Conductor = series
Dielectric = shunt

A transmission line is a bunch of capacitors and resistors.


A transmission line can be visualized as a series of LC not RC circuits.


My point being it can be analyzed as a network of discrete components.
