The congestion and expansion of the Electromagnetic spectrum calls for methods to better utilize it. Notably, traditional narrow-band approaches dictate the use of multiple antennas operating separately, leading to redundancies and inefficiencies. By contrast, ultra-wideband (UWB) arrays can consolidate multiple frequency bands into a single aperture, to lower space requirements, cost, weight and power consumption. Especially, the FR-bands dedicated to the 5G/6G communications are extremely fragmented, with operating frequencies spread across the microwave to mm-Wave spread. This paper proposes a solution to unify the disperse FR bands under a single UWB antenna array.
