Abstract: A method of tuning an electrically small antenna comprising a radiating element and a support structure comprises applying a force to the support structure to change a shape or a dimension of the radiating element to increase or decrease a frequency at which the electrically small antenna resonates.

Abstract: A multi-resonant, electrically-small antenna having a first helical arm and a second helical arm. The first helical arm encircles a first central axis and includes a proximal end. A radius between the first helical arm and the first central axis decreases in a distal direction away from the proximal end of the first helical arm. The second helical arm is nested in the first helical arm and encircles a second central axis. The second helical arm also includes a proximal end. A radius between the second helical arm and the second central axis decreases in a distal direction away from the proximal end of the second helical arm.

Abstract: An antenna system comprises a substrate, an antenna positioned on the substrate, and a circuit component positioned on the substrate. The antenna is positioned on a first surface of the substrate and operable to emit a radiation pattern. The circuit component is positioned on the substrate in a null region of the radiation pattern. The thickness of portions of the substrate are modified to achieve a desired performance characteristic of the antenna.

Abstract: A method of manufacturing a compound object, such as an antenna, is disclosed. The method includes creating, via additive manufacturing, a first component formed at least in part of an oxidizing metal; applying, via vapor deposition, a solderable coating to at least a portion of the first component; and soldering at least a portion of the first component to a second component by applying a solder to the solderable coating of the first component. The oxidizing metal may be a titanium allow, such as Ti-6Al-4V. The solderable coating may include copper and/or tin-lead.
