摘    要:针对短波天线小型化问题,通过分析燕尾型对数周期天线的工作原理,设计出了一种小型化短波转动对数周期天线.在小尺寸限制下,通过感性加载与L型加载集合的方式,有效地扩展了转动对数周期天线的最低工作频率.该天线可工作在3~30 MHz,而天线长度仅25 m.仿真与实际测试结果表明:该天线电压驻波比小于2.5,增益8 dBi,能够有效地进行2 000 km通信.

关 键 词:对数周期天线  小型化  短波

Abstract:Based on the miniaturization of high frequency (HF) antenna, a miniaturized rotated log-periodic HF antenna is designed by analyzing the theory of the cable of coattails log-periodic antenna. Limited in small structure, it is combined inductance loaded and L structure loaded so that the lowest work frequency of rotated log-periodic antenna is effectively extended. The designed antenna can work in 3~30 MHz, however, its length is only 25 m. Simulation and test results show that the voltage standing wave ratio(VSWR) of the antenna is less than 2.5, the typical gain is 8 dBi, the new designed antenna can be used in communication in 2 000 km.
Keywords:log-periodic antenna  miniaturization  HF
