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.
