Flex-Coils combine antenna coils and flexible or rigid-flex circuits in one rugged package. Coils with wire as small as AWG 50 allow high sensitivity in a flat laminated package, and etched coils provide a total thickness of less than 0.010 in. Polyimide insulation boasts high dielectric strength, flexibility, and protection for the antenna.

When integrated with a flexible or rigid-flex circuit, Flex-Coils are said to improve reliability, lower parts count, simplify assembly, and reduce rejects. They can be designed in round, rectangular, oval, and other shapes to meet specific packaging requirements. In addition, they can be supplied flat or pre-formed to precise dimensions.

Applications include implantable medical devices, high precision position sensing, and non-destructive test machinery.
