| 摘 要： | 针对波束倾角可控天线的小型化和低成本,设计了宽频带双缝隙耦合矩形微带天线单元,组成1×8元线阵,采用2套基于Wilkinson不等功分器的馈电网络实现切比雪夫的幅度分布。具有不同相位差的2套馈电网络,通过不同的缝隙耦合对同一微带单元口径面馈电,分别形成了2种倾角的波束。仿真结果表明,共口径双缝隙耦合微带天线阵实现了90°和75°两种波束倾角的可控切换,是一种体积小、造价低的方向图可重构天线。

| Abstract: | Considering the problem of compact and low price of steered beam antenna, a kind of wide-band microstrip patch based on double coupling slots is designed. The 8 cells line arrays obtains Chebyshev distribution using Wikinson power devider with unequal output. The shared-aperture of microstrip arrays is fed with double coupling slots by double feeding networks of different phase. Simulation results show that the line arrays can switch beams between 90°and 75°. The microstrip patch arrays based on shared-aperture and double coupling slots is a kind of small size and low cost patten reconfigurable antenna. |
