摘　　要：介绍一种工作在3~30 MHz的宽带、圆极化、高仰角、短波小型化天线。天线以对数螺旋线为基本结构，具有底端RLC集总元件的复合加载结构，并采用矩量法进行天线设计和优化。天线尺寸在25 m×25 m×10 m范围内。实践表明，该天线具有占地小、架设简便、效率高、200 km范围内无盲区等优点，可广泛应用于短波机动通信领域。A broadband circular polarization high-elevation-angle shortwave miniaturization antenna working in the 3~30 MHz is introduced in this paper. The logarithmic spiral is used as the basic structure of the antenna,which has composite loading structure with bottom RLC lumped element. The moment method is adopted for the antenna design and optimization. The size of the antenna is within the range of 25 m × 25 m × 10 m. It has the advantages of small land occupation,high efficiency, easy erection and no blind area within 200 km. It can be widely used in the field of shortwave mobile communication.
