Higher signal isolation solutions for printed circuit board mounted antenna and waveguide interface
First Claim
1. A waveguide mounted onto a dielectric substrate so as to enclose around a periphery of an antenna and contain radiation produced by the antenna along a path that is coaxial with a centerline of the waveguide, the waveguide comprising:
- a first portion comprising a first cross sectional area that is substantially polygonal that transitions to a second cross sectional area that is substantially conical, wherein a shape of the radiation produced by the antenna is altered by the first portion as the radiation propagates through the first portion;
a second portion comprising an elongated tubular member coupled with the first portion; and
a dielectric block disposed within the waveguide, the dielectric block comprising a square section and a conical section.

Abstract
Higher isolation solutions for printed circuit board mounted antenna and waveguide interfaces are provided herein. An example waveguide mounted onto a dielectric substrate can enclose around a periphery of an antenna and contain radiation produced by the antenna along a path that is coaxial with a centerline of the waveguide. The waveguide can have a first portion having a first cross sectional area that is substantially polygonal that transitions to a second cross sectional area that is substantially conical. A shape of the radiation produced by the antenna is altered by the first portion as the radiation propagates through the first portion. A second portion includes an elongated tubular member coupled with the first portion.
