Microstrip Transmission Line - Lesson 3

This video lesson describes a microstrip transmission lines as a planar approximation of the lower half of a coaxial cable. It is composed of a conducting plane which is covered in a layer of dielectric, with a second conducting trace on top of the dielectric. The electric field is mostly contained in the dielectric, but it also fringes up above the dielectric into the free space region. A microstrip transmission line is easy to fabricate in-house and customize to your own requirements, but the fact that the fields are exposed means that it is susceptible to interference.
