Waveguide interface with a launch transducer and a circular interface plate
First Claim
1. A waveguide interface comprising:
- a launch transducer comprising one or more transmission lines in a first portion of the launch transducer and at least one antenna element coupled to the one or more transmission lines in a second portion of the launch transducer, wherein the at least one antenna element is configured to radiate millimeter wave frequency signals;
a support block including a printed circuit board, the support block oriented along a plane;
a communication device coupled to the printed circuit board, wherein the launch transducer is positioned adjacent to and coupled to the communication device;
a circular interface plate coupled to an end of the support block and oriented perpendicular to the plane, the interface plate having a rectangular slot having predetermined dimensions, wherein the interface plate is positioned flush against a standard waveguide flange such that the narrow dimension of the rectangular slot within the interface plate is orthogonal to a H-field dimension of the standard waveguide flange; and
a waveguide component coupled to the interface plate, the waveguide component having a waveguide opening, wherein the first portion of the launch transducer is positioned within the rectangular slot such that the rectangular slot prevents energy from the transmission line from being emitted toward the printed circuit board or the waveguide opening and allows energy to pass from the at least one antenna element into the waveguide opening.

Abstract
A waveguide interface and a method of manufacturing is disclosed. The interface includes a support block that has a printed circuit board. A communication device is coupled to the circuit board. A launch transducer is positioned adjacent to and coupled to the communication device. The launch transducer includes one or more transmission lines in a first portion and at least one antenna element in a second portion. The antenna element radiates millimeter wave frequency signals. An interface plate coupled to the support block has a rectangular slot having predetermined dimensions. A waveguide component is coupled to the interface plate and has a waveguide opening. The first portion of the launch transducer is positioned within the slot such that the slot prevents energy from the transmission line from emitting toward the circuit board or the waveguide opening but allows energy to pass from the antenna element into the waveguide opening.
