摘要：
The design, analysis, and measurement of a reconfigurable null scanning antenna operating at 2.4 GHz are presented. Unlike existing null reconfigurable antennas, this compact antenna scans its pattern null continuously, and maintains its impedance bandwidth without the need for feed reconfiguration. Incorporation of 12 varactors enables null reconfiguration. Full-wave simulations of the antenna, including the bias network and the lumped circuit model for the varactors, predict antenna performance. Impedance and pattern measurements verify simulated results.
