任意极化波导缝隙天线

Design of Arbitrary Polarized Waveguide Slotted Array Antenna

设计一种可以辐射任意线极化波的波导缝隙天线单元。在脊波导的基础上进行设计。结构紧凑、馈电方便。多个同种极化状态的缝隙单元组成线阵之后,如果将拥有一种任意线极化状态(如+45°线极化)的线阵和拥有另一种任意线极化状态(如-45°线极化)的线阵交错排列组成二维阵列,再借助适当的馈电网络,就可以实现任意极化,且两个任意线极化信号的频率可以相同也可以不同。

A waveguide slotted array antenna element,which can radiate arbitrary linear polarized signal,is proposed in this paper.It is constructed on the basis of a ridged wavegnide.The structure is compact and the feed of the antenna is convenient.By interlacing a slotted array exhibiting a polarization state with a slotted array exhibiting another polarization state,a common antenna structure to support the communication of electromagnetic signals having a pair of arbitrary polarization states can be achieved.
