本文主要介绍带有边环法兰盘园形表面波平面反射器,并以双绕螺旋背射天线为馈源的新型高性能园极化背射天线基本原理、方案及其在红外传输自跟踪系统实验中所取得的实用性结果。文中简述了研制概况及方案选择的基点,给出了天线详细设计数据,各部分的性能,测试结果,实验数据、曲线等。实验结果表明所研制的这类天线在增益、旁瓣电平,相位特性、辐射方向图等方面得到了满意的结果,与同类天线比较主要性能具有明显改进。
This paper mainly introduces the basic principle and scheme of a new type of high-performance circular polarization back-fed antenna with circular-ring flanged circular surface wave flat reflector and dual-spiral back-fired antenna as its feed, Practical results obtained in system experiments. In this paper, the basic situation of research and scheme selection is briefly described. The detailed design data of the antenna, the performance of each part, the test results, the experimental data and the curve are given. The experimental results show that the developed antenna has obtained satisfactory results in terms of gain, sidelobe level, phase characteristic, radiation pattern, etc. Compared with similar antennas, the main performance has been significantly improved.
