US Patent 7365699 Independently center fed dipole array

A dipole array is provided for use as an Ultra Short Pulse (USP) transmitter or receiver in UWB communications systems, which reduces the output pulse dispersion. Instead of having all the dipole elements serially fed by a transmission line, the feeding in the array is made independently through a central point and the radiation is emitted and received broadsided with respect to the array plane. This configuration minimizes the relative time delay between radiating resonance frequencies.
