A Novel Design of Reconfigurable Annular Slot Active Patch Antenna

摘要：

　　This paper presents a novel reconfigurable annular slot structure.The proposed antenna has a functional dual branch microstrip line components being coupled with annular slot to create circular polarized radiation.Two PIN diodes are embedded to the dual branch microstrip line and excited by Vdc=3V and Idc=150 mA.Reconfigurable circular polarizations,including linear,right-handed and left-handed polarizations can be simply alternated by shifting the modes of pin-diode.Simulation and experimental results have shown the good impedance bandwidth for return loss and antenna gains in circularly polarized states.
