Abstract
The present application discloses embodiments that relate to an electromagnetic apparatus. In one aspect, the present apparatus includes a circuit board configured to propagate an electromagnetic signal. The apparatus also includes a waveguide configured to propagate an electromagnetic signal. The apparatus further includes a coupling port configured to couple a signal between the circuit board and the waveguide, where the coupling port has dimensions based on a desired impedance of the port.
Claims20
A method comprising:
- forming a first portion of a waveguide channel in a top block;
- forming a second portion of the waveguide channel in a bottom block;
- coupling the first portion of the waveguide channel and the second portion of the waveguide channel together to form a waveguide having the waveguide channel;
- and
- forming a coupling port in the bottom block such that a waveguide portion of the coupling port has dimensions based on a desired impedance, wherein the coupling port is configured to couple electromagnetic energy between a circuit board and the waveguide such that the waveguide propagates the electromagnetic energy via the waveguide channel.
A system comprising:
- a top block;
- a bottom block;
- a machine tool;
- and
- a computing device configured to:
- form, using the machine tool, a first portion of a waveguide channel in the top block;
- form, using the machine tool, a second portion of the waveguide channel in the bottom block;
- cause the first portion of the waveguide channel and the second portion of the waveguide channel to couple together to form a waveguide having the waveguide channel;
- and
- form, using the machine tool, a coupling port in the bottom block such that a waveguide portion of the coupling port has dimensions based on a desired impedance, wherein the coupling port is configured to couple electromagnetic energy between a circuit board and the waveguide such that the waveguide propagates the electromagnetic energy.
An article of manufacture including a non-transitory computer-readable medium having stored thereon instructions that, when executed by a processor cause the processor to perform operations comprising:
- forming, using a machine tool, a first portion of a waveguide channel in a top block;
- forming, using the machine tool, a second portion of the waveguide channel in a bottom block;
- causing the first portion of the waveguide channel and the second portion of the waveguide channel to couple together to form a waveguide having the waveguide channel;
- and
- forming, using the machine tool, a coupling port in the bottom block such that a waveguide portion of the coupling port has dimensions based on a desired impedance, wherein the coupling port is configured to couple electromagnetic energy between a circuit board and the waveguide such that the waveguide propagates the electromagnetic energy.
