本文讨论了在方位面和仰角面同时配置偶极子和定向单元的数字天线阵的使用问题。特别是，他们调查的VHF范围低于1 GHz的通信信道。这一范围的特点是分布广泛。然而，它的应用充满了许多困难，如衰减，从粗糙表面的反射等，这些问题的解决方案之一可以是方位-仰角数字波束形成。本文提出了在VHF范围内的信号在自由空间中的传播的仿真结果，考虑到这些频率的噪声特性。假设在发射侧使用对称偶极子，并且在接收数字天线阵列（DAA）上的定向八木天线也配备有偶极子。仿真了接收数字天线阵元的圆形（CAA）和半十二面体的排列形状。根据发射机和接收机之间的距离估计的比特错误率（BER）。
In the paper the problem of using digital antenna arrays equipped with dipole and directive elements simultaneously in the azimuth and elevation planes is discussed. In particular, they are investigated for communication channels of the VHF range below 1 GHz. This range is characterized by the fact that it has found wide distribution. However, its application is fraught with many difficulties, such as attenuation, reflection from rough surfaces, etc. One of the solutions to these problems can be azimuth-elevation digital beamforming. The paper presents the simulation results for the propagation of signals in the VHF range in free space, taking into account the noise characteristic of these frequencies. It is assumed that a symmetrical dipole is used on the transmitting side, and a directional Yagi antenna on the receiving digital antenna array (DAA) also equipped with a dipole. The circular (CAA) and hemi-dodecahedron shapes of the arrangement of elements of the receiving digital antenna array are simulated. The bit error rates (BER) depending on the distance between the transmitter and the receiver are estimated.
