ABSTRACT:
A conductive coil, designed to be used as an inductance in a resonant cavity, comprises a metal strip integrally cut or etched from a sheet with a branch diverging from the main stem of the strip in the vicinity of one extremity thereof bent at an obtuse angle, that extremity ending in an enlarged terminal tab serving as a ground connection. After formation of the strip, the terminal tab is bent at right angles to the extremity whereas a major strip portion is helically wound about an axis in line with the center of the terminal tab.
