An FIR-filter controlled linear antenna array for ultra wideband short pulses will be presented in this article. Spatial processing is a promising technique in order to significantly increase the data rate in wireless pulsed transmission systems. It enables beam pointing toward desired signals and null steering to reduce interference with spurious signals or multipath components. In this article, an Finite Impulse Response (FIR) filter controlled linear antenna array for ultra wideband short pulses will be presented. The paper reports the design procedure for ultra wideband radiation pattern. A mathematical framework is given allowing the consideration of antenna and channel characteristics. Finally, we demonstrate the performance of the FIR-filter technique by means of a typical short pulse transmission system, where the line of sight signal is improved in terms of gain and pulse shape, and multipath components are desirably minimized.
