Claims
- 1. A waveguide feed apparatus for providing a transition into/out of a waveguide, comprising:
- a conductive arm having a probe portion that is capable of sensing/radiating electromagnetic energy within the waveguide, said conductive arm having a predetermined shape;
- a dielectric material encapsulating said conductive arm and maintaining said conductive arm in said predetermined shape;
- a conductive back-short portion coupled to said dielectric material and forming a back-short for said probe portion;
- said dielectric material holds said probe portion in fixed relation to said conductive back-short portion; and
- said conductive back-short portion and said conductive arm are both formed from a single sheet of conductive material.
- 2. The waveguide feed apparatus, as claimed in claim 1, wherein:
- said dielectric material is injection molded about said conductive arm.
- 3. The waveguide feed apparatus, as claimed in claim 1, wherein:
- said conductive arm is formed from a single sheet of conductive material and is bent into said predetermined shape.
- 4. The waveguide feed apparatus, as claimed in claim 1, wherein:
- said single sheet of conductive material is formed into a lead frame.
- 5. The waveguide feed apparatus, as claimed in claim 1, wherein:
- said dielectric material includes an outer dimension that is tailored to an internal dimension of the waveguide.
- 6. The waveguide feed apparatus, as claimed in claim 1, wherein:
- said dielectric material has a cylindrical outer shape.
- 7. A waveguide feed apparatus, comprising:
- at least one probe portion for use in radiatingl/sensing electromagnetic energy within a waveguide; and
- a back-short portion for providing an electrical back-short for said at least one probe portion, said back-short portion being conductively isolated from said at least one probe portion;
- wherein an area between said back-short portion and said at least one probe portion is at least partially filled with a dielectric molding material so that said at least one probe portion is held in fixed relation to said back-short portion; and
- said at least one probe portion and said back-short portion are formed from a single sheet of conductive material.
- 8. The waveguide feed apparatus, as claimed in claim 7, wherein:
- said dielectric molding material is injection molded into said area.
- 9. The waveguide feed apparatus, as claimed in claim 7, wherein:
- said at least one probe portion and said back-short portion are conductively coupled to one another when initially formed.
