International Classification:

H01P 5/107
H01P 3/08
H01P 1/02
H01P 3/12
H01Q 9/04

Abstract:

A microstrip-to-waveguide transition includes a substrate and a waveguide. The substrate has a metal layer, a ground layer and a dielectric layer disposed between the metal layer and a ground layer. The substrate includes a microstrip line impedance transformer and a substrate integrated waveguide that is electromagnetically coupled to the microstrip line impedance transformer. The substrate integrated waveguide has a 90 degree substrate integrated waveguide bend section at an end portion thereof. The waveguide is arranged perpendicularly relative to the substrate. The waveguide is electromagnetically coupled to the substrate integrated waveguide at the 90 degree substrate integrated waveguide bend section. The microstrip-to-waveguide transition is free of a back-short at a location corresponding to the 90 degree substrate integrated waveguide bend section.

Assignee:

Hughes Network Systems, LLC - Germantown MD

International Classification:

H01P 3/12

Abstract:

An integrated waveguide for use in high radio frequency communication is provided. The integrated waveguide including: a first substrate including a first plastic layer having on a first inward-facing surface, a first portion of a waveguide feature formed on the first inward-facing surface, and a metal layer disposed on the first inward-facing surface; and a second substrate including a second plastic layer having a second inward-facing surface, a second portion of a waveguide feature formed on the second inward-facing surface, and a metal layer disposed on the second inward-facing surface, wherein the first substrate and the second substrate are assembled to define an integrated waveguide feature defined by an assembling of the first portion of the waveguide feature and the second portion of the waveguide feature.
