本文给出了一种通过修改曲线微带天线贴片形状以改善其性能的实验研究方法。文中采用等效直线阵法定性分析曲线微带天线在两个主平面内的方向特性,并用以指导对贴片形状之修改。已得到了一些初步成果:在主平面内可分别作到±60°和±30°范围内轴比小于3dB;波束倾斜的缺陷也有所改善。
In this paper, we present an experimental method to improve the performance of microstrip patch by modifying the shape of microstrip antenna. In this paper, the equivalent linear array method is used to qualitatively analyze the directional characteristics of the curved microstrip antenna in the two main planes and to guide the modification of the patch shape. Some preliminary results have been obtained: the axial ratio within ± 60 ° and ± 30 ° in the principal plane are respectively less than 3dB; and the defect of beam tilt is also improved.
