摘要
运用HFSS对窄边波导缝隙行波阵进行仿真设计,提出一种切实可行的设计方法。在初始设计完成之后,调整缝倾角和缝深,分别使天线口面的幅度和相位分布逼近设计值,经过几次循环,最终得到了某Ku频段阵列仿真副瓣低于-38.5dB、实测副瓣低于-35.5dB的结果。
A feasible method for the design of traveling-wave-fed sidewall slot arrays with HFSS is present.The design process falls into two steps: the original design and correction design.After the original design,the inclination angles and depth of slots are adjusted to approach the distribution of design.Finally,the result that the sidelobe level is-38.5dB in simulation and-35.5dB in measurement is obtained after the iterative adjustments.
