Abstract
Abstract An angular coaxial connector for use in ultrahigh frequency systems where the impedance of the conductor must be kept within a minimum tolerance to avoid unwanted reflections. To avoid complicated structures, air is used as the dielectric in the bend portion of the angle and the radius of the air and insulator portions of the system is so proportioned that the voltage standing wave ratio (VSWR) is maintained at 1 and the impedance of the line is constant.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
135 words
A coaxial connector, extending 90° along a circular arc, for high frequency applications comprising: an outer tubular sheath extending 90° along a circular arc and made of a conductive material having an inner surface defining a space for an air dielectric, said tubular sheath including annular recessed portions disposed adjacent each end thereof, said annular recesses being in the internal surface of the tubular sheath; a cylindrical solid insulator material disposed in each annular recess; and a central conductor extending 90° along a circular arc and concentrically through said solid insulators and the tubular air space within said sheath between said insulators; the radial thicknesses of the solid insulator materials and the radial thickness of the air space in combination with their dielectric constants providing a constant ohmic impedance in all portions of the line.
Claim 2
Dependent Claim
