Abstract
An electronic stripline circuit includes a flexible dielectric film having a three-dimensional coiled shape that defines a spiraled inner core. At least one electrically conductive signal trace is formed on a first surface of the flexible dielectric film. The signal trace extends along a signal path to define a trace length configured to control a time delay of a coiled time delay unit.

An electronic stripline circuit, comprising:
- a flexible dielectric film having a three-dimensional coiled shape that defines a spiraled inner core;
- at least one electrically conductive signal trace formed on a first surface of the flexible dielectric film, the signal trace extending along a signal path to define a trace length configured to control a time delay of a coiled time delay unit, the at least one signal trace having a meandering pattern that extends between a first terminal end and a second terminal end formed on the stripline circuit;
- and
- a dielectric layer disposed on the at least one signal trace,
- wherein the flexible dielectric film comprises:
- a first metal clad layer having a ground plane formed thereon;
- and
- a second metal clad layer including the at least one signal trace formed thereon.
