We propose a new antenna array concept called Independently Center-fed Dipole Array (ICDA) for Ultra Short-Pulse (USP) applications. The characteristics of a 12-element ICDA array were numerically analyzed. By using Finite-Difference Time Domain (FDTD), we show that the workable frequency range of ICDA is the sum of all its elements bandwidth. The transmission coefficient is linear, in terms of amplitude and phase, from 3.1GHz to 10.6GHz.
