中文摘要:
      为了实现贴片天线在弹载末制导上的应用,提出了基于相位梯度的定向贴片天线。利用相位梯度超表面能够改变电磁波传播方向的特性,设计了一款辐射主波瓣大角度偏离法向的贴片天线。该天线由7个H型贴片组成,通过优化结构参数,得到了所需要的相位梯度。仿真和测试结果显示,由于相位梯度的引入,在工作频率为9.6 GHz时,天线主波瓣的最大增益方向偏离法向45°
英文摘要:
      In order to realize the application of patch antenna in missileborne terminal guidance, a new directivity patch antenna based on the phase gradient is designed. This paper utilizes phase gradient metasurface for changing the characteristics of electromagnetic wave propagation in direction, and designs a new patch antenna whose main lobes are deviated from normal of patch antenna at large angle. The antenna consists of seven Hshaped patches, and a desired phase gradient is obtained by optimizing the structure parameters. The results show that with the introduction of phase gradient, the main lobes of the antenna deviated from normal are about 45° in maximum gain direction while operating frequency is 9.6 GHz.
