Flip-chip technology separate page History of coplanar waveguide Coplanar waveguide was invented by Cheng P. Wen, check out his picture in our Microwave Hall of Fame! Wen explains that his original name for coplanar waveguide was "planar strip line". A co-worker, Lou Napoli suggested the name coplanar waveguide.

Back cover copy Up-to-date coverage of the analysis and applications of coplanar waveguides to microwave circuits and antennas The unique feature of coplanar waveguides, as opposed to more conventional waveguides, is their uniplanar construction, in which all of the conductors are aligned on the same side of the substrate. This feature simplifies manufacturing and allows faster and less expensive characterization using on-wafer techniques. Rainee Simons thoroughly discusses propagation parameters for conventional coplanar waveguides and includes valuable details such as the derivation of the fundamental equations, physical explanations, and numerical examples.

Nonreciprocal devices[ edit ] Nonreciprocal gyromagnetic devices depend on the microwave signal presenting a rotating circularly polarized magnetic field to a statically magnetized ferrite body. CPW is designed to produce just such a rotating magnetic field in the two slots between the central and side conductors. The dielectric substrate has no direct effect on the magnetic field of a microwave signal travelling along the CPW line. For the magnetic field, the CPW is then symmetrical in the plane of the metalization, between the substrate side and the air side. Consequently, currents flowing along parallel paths on opposite faces of each conductor on the air-side and on the substrate-side are subject to the same inductance, and the overall current tends to be divided equally between the two faces. Conversely, the substrate does affect the electric field, so that the substrate side contributes a larger capacitance across the slots than does the air side.
