1. A device, comprising:
- a dielectric substrate;
an electrical feed;
an antenna mounted onto the dielectric substrate and connected to the electrical feed, the antenna having a substantially square shape; and
a waveguide mounted onto the dielectric substrate so as to enclose around a periphery of the 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, the waveguide further comprising a second portion comprising an elongated tubular member coupled with the first portion.

Abstract
Higher isolation solutions for printed circuit board mounted antenna and waveguide interfaces are provided herein. An example device includes any of a dielectric substrate or transmission line, an antenna mounted onto the dielectric substrate, and an elongated waveguide mounted onto the dielectric substrate so as to enclose around a periphery of the antenna and contain radiation produced by the antenna along a path that is coaxial with a centerline of the waveguide, the elongated waveguide having a first cross sectional area and a second cross sectional area, and the first cross sectional area differs from the second cross sectional area.
