摘　　要：通过对共口径双波段天线的研究,提出了一种新型共口径双波段波导缝隙阵列天线设计方法。该方法适用于设计由工作于不同波段的两个脊波导缝隙阵天线同层间隔排布组成的高性能天线,特别适用于小型双波段雷达天线设计。详细描述了如何减弱两个波段相互干扰对天线性能的影响。最终通过一个Ku/Ka共口径双波段波导缝隙阵列天线设计与测试,其测试结果与仿真结果吻合度高,验证了设计方法的正确性。A co-aperture dual-band waveguide slot array antenna design method is proposed by studying co-aperture dual-band array antennas.This method is suitable for designing a high performance antenna composed of two ridge waveguide slot arrays operating in different bands.This antenna is especially suitable for small dual-band radars.This paper describes in detail how to reduce the effect of mutual interference between two bands on antenna performance.Finally,some design and test results of Ka/Ku antennas are given.The test results are in good agreement with the simulation results,verifying that the design method is correct.
