摘　　要：基于固态等离子体表面P-I-N(S-PIN)二极管设计了一款可重构天线,该天线用多个S-PIN单元代替金属作为辐射器。在一种激励模式下,天线作为单极子天线辐射;在另一种激励模式下,天线作为偶极子天线进行辐射。天线实现了X波段到Ka波段的频率可重构,即在X波段和Ka波段分别有2个工作频点,2个频段均有广泛用途,可适用于一些要求宽频带范围内频率可重构的场合。A reconfigurable antenna based on a solid state plasma S-PIN diode is designed,which uses a plurality of S-PIN units instead of metal as the radiator.In one excitation mode,the antenna acts as monopole antenna;in another excitation mode,the antenna is radiated as dipole antenna.The antenna achieves frequency reconfiguration from X band to Ka band,which means that it can work well both in X band and Ka band.The two frequency bands have wide range of applications.It can also be applied to some occasions requiring frequency reconfiguration in wide frequency band.
