摘　　要：根据短波传输的特点设计并研究了一种水平极化的全向振子阵。基于矩量法对其进行了仿真和计算,得出水平面和垂直面的辐射方向图,并进行了详细的分析和比较,给出了利用矩量法求解天线问题的一般思路。结果表明:此类振子阵具有水平面的全向性和垂直面的强方向性。在实际使用中可根据不同要求对天线进行选型。A types of level omnidirectional arrays of antenna is designed and studied according to the characteristics of short - wave. The E - plane and H - plane radiation pattern of the antenna are calculated numerically by Moment Mothod. Moment method is introduced here and that how to solve the problerms of antenna using this method is also introduced. In addition, the results obtained is analyzed and compared, which can indicate that the arrays have the characteristic of omnidirectional in level and strong direction in vertical. It also provides the choices of antenna used on different needs of practice.
