A circular helix has been a popular slow-wave structure but it cannot be fabricated using printed-circuit techniques. In this project, it is proposed to investigate a new type of slow-wave microwave structure which can be fabricated using printed-circuit techniques and which emulates the features of a circular helix. A planar waveguide structure, with slow-wave properties similar to those of a circular helix, confined planar helix is being investigated. It can be fabricated using printed-circuit techniques. For this project, propagation constant, phase velocity, interaction impedance and electric field are examined to assess the usefulness of the structure for a travelling-wave tube.This project involved the use of CST Microwave Studio.
