Compact Ultra-Wideband (UWB) Antenna (CUA)

The invention, the compact ultra-wideband (UWB) Antenna (CUA), evolved from research in VTAG (Virginia Tech Antenna Group) based on the implications on fundamental limits on antenna size. The CUA is very close to the theoretical minimum size, but without sacrificing efficiency or gain.

The invented CUA has at least 10:1 instantaneous bandwidth and nearly constant omni-directional radiation patterns, high efficiency (>95%) and 5dBi realized gain over the entire band. In addition, the antenna provides a short pulse radiation characteristic. The electrical size of the CUA is approximately 1/10 wavelength at the lower bound of the band, which is two times smaller than conventional ultra-wideband antennas.

The invented antenna occupies a hemispherical volume with no additional loading material used. Thus, the antenna is light, cheap and unobtrusive. In addition, the invented antenna meets aerodynamic design requirements. Because the antenna requires only a few small connection points between the antenna and ground plane, the antenna can be easily installed and integrated on a curved surface.
