International Journal of Antennas and Propagation, Volume 2026, Issue 1, 2026.A novel linear active rampart array that is able to steer in the azimuth plane through frequency sweeping and in the elevation plane through phase shifting has been developed. The presented system uses eight active elements and two parasitic ones to ensure consistent radiation patterns.
