A compact mobile high-frequency Antenna that quickly and quietly self-adjusts to minimize Voltage Standing Wave Ratio (VSWR). Includes a compact tuning coil and a rolling contact. A Reentrant cap serves as a capacitive top hat. A spiral cut enhances the efficiency is this very short antenna. A tough insulating tube covers the antenna to serve as a radome protect the user from RF burns. The use of rolling contacts on a smooth inside diameter of the tuning coil greatly reduces the force to move the contactor as well as the acoustical noise generated when tuning. A controller drives a servo motor to position the contactor to the optimal position within the tuning coil and selects the impedance to connect between the unused end of the tuning coil and the feed point of the antenna to optimize VSWR.

The disclosed system may include an antenna and an antenna matching network. The antenna matching network may include an aperture tuner configured to shift a frequency response of the antenna and an impedance tuner configured to dynamically change an amount of radiated power for the antenna. The antenna matching network may be positioned at least a specified minimum distance from the antenna according to various operating characteristics of the antenna. Various other apparatuses, wearable electronic devices, and methods of manufacturing are also disclosed.
