Appl. No.:

16/790785

Inventors:

- Lisle IL, US
James M. Post - Elkhart IN, US
Robert L. Newman - Edwardsburg MI, US

Assignee:

CTS Corporation - Lisle IL

International Classification:

G01R 29/08
H01Q 1/12
H01Q 1/42

Abstract:

A radio frequency antenna with a two-piece sealing ferrule. The antenna includes a center antenna and an outer tube surrounding the center antenna. A mounting nut surrounds and is slidable relative to the outer tube. An outer ferrule surrounds and is slidable relative to the outer tube. An inner ferrule that is separate from the outer ferrule surrounds and is fixed to the outer tube. A mating nut is secured to the mounting nut. The threading of the mounting nut and the mating nut together results in the wedging between the inner and outer ferrules which results in the exertion of a first compressive force by the inner ferrule against the outer tube for sealing the inner ferrule and the outer tube and the exertion of a second compressive force of the inner ferrule against the mating nut for sealing the inner ferrule and the mating nut.

Abstract:

A radio frequency antenna comprising an inner conductor or antenna surrounded by and spaced from an outer sleeve, the space between the inner conductor and the outer sleeve being filled with a granular or powder insulating material. A sealant material covers a first end of the outer sleeve for sealing and retaining the insulating material in the antenna. A method of making the antenna includes the step of bending the inner antenna and the outer sleeve during assembly following the steps of filling the space between the inner conductor and the outer sleeve with the insulating material and sealing the insulating material in the antenna. In one embodiment, the radio frequency antenna is adapted for transmitting and receiving radio frequency signals in a radio frequency vehicle exhaust control and sensor system.
