摘 要：相控阵天线以其灵活的波束控制能力得到了广泛的应用，原理是通过天线单元的移相器实现能量的空间合成，这就需要大量的移相器，增加了成本、体积、重量。本文研究频率分集阵列，无须移相器，通过频率编码设计实现了对空间和距离二维波束控制，并通过仿真验证了设计的正确性。

Abstract：Phased array antennas are widely used for their flexible beam control capabilities. The main principle is to achieve space energy synthesis by the phase shifter of the antenna unit. However，phased array antenna requires a large number of phase shifters，this will increase the cost，volume，and weight. This paper studies frequency diversity array without phase shifter，and realizes space and distance two dimensional beam control through frequency coding. The correctness of the design is verified by simulation.
Keywords：array antenna；frequency diversity array；frequency coding
