| 摘 要： | 本文给出了一种Ka 波段对称四波束波导缝隙行波阵列天线的设计方法。该设计对经典行波阵理论进行了改进
和创新，提出将驻波阵的电流幅度分布理论应用于行波阵，推导出多波束波导缝隙的电场分布方程，实现了波导缝
隙阵列天线对称四波束配置，并具备共口径、高增益、低副瓣等优点，满足多普勒测速雷达对天线的要求。HFSS
软件仿真测量结果验证了该设计的正确性。

| Abstract: | This paper present a design of waveguide Slot Travelling Array Antenna with Four Symmetrical Beams at
Ka-Band .The
Design improve the conventional theory of travelling wave array antenna with introducing the amplitude distribution of
standing wave array antenna ,gives the equation of e-field distribution of radiant Slot on waveguide ,so that an Waveguide
slot array antenna with four symmetrical beams is achieved, which has a shared-aperture , a high gain and slow side lobe
level. The design absolutely meets the full needs of Doppler radar to a antenna. The results of Simulation and
measurement show that the design is accurate. |
