Transmission characteristics of planar tape-helix: Simulation and measurements

Transmission characteristics of a planar tape- helix slow-wave structure (SWS) with straight-edge connections (PH-SEC) immersed in a homogeneous dielectric medium are presented. The SWS is designed to operate over 2-5 GHz frequency range. The measured S- parameters of the fabricated SWS show a good agreement with the simulation results. Phase velocity estimated from measured results shows a good match with that from the previously reported tape-helix analysis of the PH-SEC. These results validate the accuracy of tape-helix analysis of PH-SEC.
