Shielded Single Wire -- Ground Plane

This configuration is applicable to coaxial cables or individually shielded wires in a circular shield that are routed near a ground plane.

Height is the distance in meters from the surface of the ground plane to the center of the shield.  Height must be greater than the shield radius.

Offset is the distance in meters from the center of the shield to the center of the wire.  Coaxial cable has an offset of 0.  Offset must be less than the shield radius minus the wire radius.

Angle θ is the clockwise angle in degrees between a vertical line that bisects the center of the shield and a line that intersects the center of the shield and the center of the wire.  If the offset is 0 (coaxial cable), Angle θ is ignored.  The value for Angle θ must be in the range 0 to 360, inclusive.

Shield diameter must be greater than wire diameter.
