School of Electronic and Information Engineering, South China University of Technology, Guangzhou Guangdong 510640, China

摘要

摘要: 提出了一种用于空间功率合成的焦散抛物曲面天线,该反射面天线是由xoz平面的一条抛物线沿着yoz平面上的另一条抛物线正交扫描所形成的,天线用8单元E面喇叭线阵进行偏馈。研究了天线的反射面结构参数对天线性能的影响以及横向偏焦电扫描特性,给出了不同辐射方向下阵列的相位配置公式。仿真和实验结果表明:提出的方案可以在给定方向合成高增益波束,与同样线阵馈电的抛物柱面天线相比,H面3dB波束宽度从8.2°下降到了5°,天线增益提高了2.2dB.

Abstract: A caustic parabolic curved antenna for spatial power combination is proposed in this paper.The reflector antenna is formed by aparabola in the xoz plane orthogonal scanning along the other parabola in the yoz plane.And antenna is offset fed with a line array of 8 E-plane sector horns.Both the impact of antenna structural parameters to the antenna performance and the electric scanning properties of the transversal displacement from focus are studied.A formula is given to configure the phases of the array for a given beam deflection angle.Simulation and experiment show that the designed antenna can combine a high gain beam at a given direction.Compared with the parabolic cylindrical antenna with the same aperture, the H-plane 3dB beam width decreases from 6.9°to 5°, and the antenna gain increases by 2.2dB.
