Advanced Ring Antenna for Vehicular Communication

Reliable communication of telemetry and command data to and from various vehicles, including rockets, missiles, and aircraft, is of critical importance for many systems. This paper presents an antenna system mounted on a cylindrical vehicle that provides a tight control of phase variation in far field within wide field of view. The antenna system overcomes limitations from earlier designs, including the need for improved location accuracy, increasing data demands, spectrum scarcity, and spectrally efficient modulation.
