Acquisition of ultra-wideband signals by array antennas requires frequency-invariant radiation characteristics over the bandwidth of the signal in order to minimize distortions. In this study, a new synthesis technique of array antennas for radiating nanosecond pulse signals is presented. In this technique, all frequency-dependent radiation characteristics of the antenna array are considered and compensated through the utilization of frequency adaptive element excitations and the implementation of a complex array factor. Simulation results are presented for an equally-spaced linear array of wire dipoles designed based on the proposed method as an example to demonstrate the synthesis approach.
