Antenna feed structure

Image Number 6 for United States Patent #7256752.

A unitary feed structure for sliding installation in a passage in the insulative core of a dielectrically-loaded antenna comprises the unitary combination of a tubular outer shield conductor and elongate inner conductor which extends through the shield conductor and is insulated from the latter. The shield conductor and inner conductor have oppositely directed radially extending connection members at an end of the feed structure, these connection members being integrally formed as part of the respective conductors so that the feed structure can be inserted as a unit into the passage in the antenna core so that the connection members engage respective connection portions formed on an end face of the core adjacent on end of the passage. Soldering of the connection members to the connection portions can be performed as a single operation so as to connect the feed structure to conductive antenna elements plated on the outer surface of the core.
