Abstract [en]

This paper presents a new configuration for creating parallel multilayer waveguides (MLW) using glide-symmetric structures with the aim of reducing the space separation between parallel waveguides. A multilayer rectangular waveguide is made by stacking several thin sheets of metal. To avoid the need for electrical contacts between these sheets, we use a new glide-symmetric structure that produces a stop-band at the desired frequency band. This configuration tries to reduce the space occupied by the periodical structures to minimize the separation between parallel waveguides in arrays. The proposed structure is easy to fabricate and has low transmission losses even at high frequencies. To demonstrate the feasibility of the proposed solution, a rectangular multilayer waveguide section at 90 GHz was designed and simulated using the proposed unit cell.
