TLDR
In this article, a waveguide is magnetically coupled with an input/output line on a second dielectric substrate through a coupling slot, and a low-loss waveguide can be realized.Abstract:
A rectangular penetration hole is formed opening in the opposite two main surfaces of a first dielectric substrate Conductors for grounding are respectively formed on the main surfaces, to cover the openings of the penetration hole A conductor layer is formed on opposite inner walls in the penetration hole of the dielectric substrate A waveguide is structured by a space surrounded by the conductors and the conductor layers The waveguide is magnetically coupled with an input/output line on a second dielectric substrate through a coupling slot Because a waveguide has walls made continuous in the dielectric substrate, a low-loss waveguide can be realized Hence, a high-performance radio frequency module can be realizedread more
