Stripline Transmission Line

Stripline is a transverse electromagnetic (TEM) transmission line medium invented by Robert M. Barrett of the Air Force Cambridge Research Centre in the 1950s. Stripline is the earliest form of the planar transmission line. It uses a conducting material to transmit high-frequency waves it is also called a waveguide. This co nducting material is sandwiched between two layers of the ground plane which are usually shorted to provide EMI immunity.

A stripline is a type of transmission line based on planar microwave circuitry. It typically consists of a conducting strip surrounded by dielectric material and sandwiched between two conducting ground plane s. The dielectric material may be of different materials and thicknesses above and below the conductor leading to inhomogeneous or asymmetrical stripline.

The Physics

Shown here is a two-port stripline transmission line constructed using copper conductor in CST Studio Suite. The model is simulated in the Time Domain Solver in the frequency range of 5 – 15 GHz.
