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.
