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 asmonopole 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.
