摘　　要：简单介绍了卡西尼卵形线的形成和卵形线族，提出了基于卡西尼卵形线的新型贴片电磁结构，并采用商业软件HFSS对雷达散射截面（RCS）随入射频率与随视角的变化进行了仿真计算。得到：在频率4-8GHz范围内，卡西尼贴片的RCS小于-8dBm，明显优于矩形贴片，约小2．2dBm。在频率6GHz，Φ=90°时，RCS随视角口的变化也优于矩形贴片。通过与相同面积的矩形贴片RCS的结果对比与简单分析，得出卡西尼卵形线贴片结构用于电磁隐身将优于相同面积的矩形贴片的结论。最后指出了卡西尼卵形线新型贴片结构在电磁隐身、天线设计等方面可能具有潜在的应用前景。The forming of Cassini oval curve and its groups are simply introduced in this paper, electromagnetic structure based on new type Cassini oval patches is proposed out, and variations of Radar Cross Section（RCS） with incidence frequency and visual angle are calculated with HFSS business soft. It＇s gotten that RCS value of Cassini patches is less -8dBm, and better 2.2dB than one of the rectangle patches between 4GHz and 8GHz. When frequency is 6GHz and Φ equates to 90°, variation of RCS with visual angle is also better. The conclusions are gotten that Cassini patches electromagnetic structure is superior to rectangle patches in equal area through comparing and simply analyzing RCS results. At last, the potential application and development of Cassini oval structure are put forward in electromagnetic stealth technology and antennae design.
