Abstract :
The paper presents a using of the finite-difference time-domain (FDTD) method for antenna arrays analysis for the mobile and stationary base stations of the radiocommunication systems. Theory base of the design of quadrate antenna array as a base element of complicated radiation structures is described; a steady phase excitation for this base array in broad frequency band is proposed. The results of computer simulation by FDTD method of frequency characteristics, the radiation patterns and near time electromagnetic field evolution of this array over finite ground plane are presented.
