This paper presents a novel structure for an adaptive fully spatially processed wideband conical antenna array. A major advantage of this configuration is the frequency invariance of the directional patterns of the array within a relatively large fractional bandwidth which makes this array a potential candidate for wideband and ultra wideband (UWB) technology applications. Furthermore, unlike conventional wideband antenna arrays which use delay lines or time-domain filters, this system relies on fully spatial processing of the incoming or transmitted signals using a single real multiplier for each antenna element, without utilising any phase shifters, digital filters or adjustable delays. Finally, due to the conical shape of the array configuration, beamforming in both azimuth and elevation angles is accomplished with symmetrical and uniform characteristics in all azimuth directions.
