摘要
加脊喇叭作为宽带天线的一种重要形式在雷达工程上的应用已愈来愈广泛。文中结合AnsoftHFSSEM软件仿真技术 ,给出了一种宽带加脊喇叭的简化设计方法 ,把加脊喇叭天线的设计分解成简单的 3个部分来进行 ,即同轴脊波导变换部分、喇叭部分、脊曲线的求解部分。该方法简化了脊曲线的求解 ,避免了繁杂的数学计算过程 ,运用Ansoft电磁场仿真软件进行优化得到较理想的结果。实测结果表明 。
As an important form of wide-band antenna, the ridged horn has been widely used in radar engineering.Basing on Ansoft HFSS EM software simulation technique,the paper suggests a method to simplify the design of wideband ridged horn,which is composed of 3 parts:i.e. the design of co axial-ridged waveguide conversion,horn,and calculation of ridged curve.The method simplifies the calculation of ridged curve,and it gets some ideal result using Ansoft electromagnetic simulation software. The test results show that the antenna matches well in a 3∶1 band frequency.
