摘要: 从高频表面波雷达天线工程的角度出发，基于对数周期天线的设计理论，优化设计了一副小型 宽带发射天线；基于端射阵理论，优化设计了一副小型宽带、具有大前后比的双鞭天线，并以此作为阵列天线的基本单元组成六元均匀线阵。文中分析了收发天线的工作原理，并给出了计算机模拟结果。Abstract: According to the requirements of engineering design for High-Frequency Surface Wave Radar (HF-SWR), at first, a small broadband transmitting antenna is optimized based on the theory of log periodic antennas. Then, based on the end-fire array theory, a small broadband twin-whip antenna with big forward to backward ratio is designed. And six twin-whip antennas are used as the fundrnental element to form 12 side plane array system. The working principle of 12 side array and the log periodic antennas are analyzed, and calculating result is given in this paper. A practical broadband antenna system for HF-SWR is designed.
