01 Oct 2004TL;DR: In this paper, a folded waveguide structure is presented farmed from microwave laminates as a space saving alternative of the rectangular waveguide, which results in a width reduction of e r -1/2 /2 over standard air filled rectangular waveguides making integrated waveguide viable at low microwave frequencies.
Abstract: A folded waveguide structure is presented farmed from microwave laminates as a space saving alternative of the rectangular waveguide. It is shown that the folded waveguide results in a width reduction of e r -1/2 /2 over standard air filled rectangular waveguide making integrated waveguide viable at low microwave frequencies. Via hole technology is used to manufacture this design, at low cost, using computer controlled drilling machines. The guide is integrated to planar circuitry using tapered stripline.

TL;DR: In this paper, the authors presented a waveguide formed by a defect channel in a honeycomb lattice photonic crystal sandwiched between two metallic plates, which is shown to be substantially wider than both square and triangular lattices for easily realizable configurations.
Abstract: This paper presents a waveguide formed by a defect channel in a honeycomb lattice photonic crystal sandwiched between two metallic plates. It is shown that the bandgap of a honeycomb lattice is substantially wider than both square and triangular lattices for easily realizable configurations.

TL;DR: In this paper, the authors investigated integrated waveguide structures for low-loss millimetre wave components, which are based around periodic dielectric structures (non-radiative perforated dielectrics waveguides) formed by cylindrical air columns in the material surrounding the core of an NRD guide, and a transition to slotline is introduced to demonstrate one possible technique to integrate 3D waveguide with planar circuitry and microwave monolithic integrated circuits.
Abstract: The purpose of this work is to investigate integrated waveguide structures for low loss millimetre wave components. The guides are based around periodic dielectric structures (non-radiative perforated dielectric waveguides) formed by cylindrical air columns in the material surrounding the dielectric core of an NRD guide. Furthermore, in the centre of the guide, a transition to slotline is introduced to demonstrate one possible technique to integrate 3D waveguides with planar circuitry and microwave monolithic integrated circuits (MMICs).

TL;DR: In this article, a waveguide was synthesized using metallized vias to form the edge of the waveguide, which are sometimes termed SIRWs (substrate integrated rectangular waveguides).
Abstract: This paper investigates forming rectangular waveguides using printed circuit boards, which would potentially offer an extremely cheap and reliable means of providing a low loss transmission line for high frequency systems. A waveguide was synthesised, using metallized vias to form the edge of the waveguide - these designs are sometimes termed SIRWs (substrate integrated rectangular waveguides).
