Abstract
A reconfigurable null scanning antenna (RNSA) capable of continuous null steering in three-dimensional space is presented. This compact antenna maintains its common impedance bandwidth through the careful combination of resonances of both the driven and parasitic patches, and the incorporation of 12 varactors enables continuous null steer. Full wave simulations predict antenna performance, whereas impedance and pattern measurements validate simulated results.
