In one example, the present disclosure describes an antenna system with at least two linear antenna arrays, each having a plurality of antenna elements. Each array is designed to transmit and receive signals from different respective spectrum bands. The first antenna array and second antenna array are arranged to form one longer, combined linear array of antenna elements. In addition, at least one antenna element is shared between the first and second antenna arrays. In one example, the first antenna array is connected to a first RF distribution and phase-shifting network to distribute RF power and impart a phase profile across the first antenna array and the second antenna array is connected to a second RF distribution and phase-shifting network to distribute RF power and impart a phase profile across the second antenna array.
