本发明报导开槽漏泄同轴电缆。传统的开槽漏泄电缆的典型结构示于附图1,这种开槽同轴电缆包含内导体1,外导体3(其上开有槽5_1、5_2……,开槽方向在导体的轴向,有相等的周期),绝缘2(填在内导体1和外导体3之间)及保护外导体3的绝缘层4。这种电缆的主要电气特性,例如漏泄波分布的均匀性,稳定性,可使用的频带宽度(指在这些频率下漏泄波的辐射是稳定的)等等,主要取决于外导体的开槽结构,例如,
The present invention reports slotted leaky coaxial cable. A typical structure of a conventional slotted leaky cable is shown in FIG. 1. The slotted coaxial cable includes an inner conductor 1 and an outer conductor 3 (grooves 5_1, 5_2, ... are formed on the inner surface of the conductor. , With an equal period), insulation 2 (filled between the inner conductor 1 and the outer conductor 3), and the insulating layer 4 protecting the outer conductor 3. The main electrical characteristics of such cables, such as the uniformity, stability of leaky wave distribution, the available bandwidth (which means the radiation of the leaky wave is stable at these frequencies), etc., depend mainly on the notched structure of the outer conductor ,E.g,
