【摘要】：提出了一种S波段宽带圆极化微带天线。该天线采用切角方形贴片实现圆极化辐射,利用差分馈电抑制高次模改善轴比,通过贴片上开双十字槽和增加空气层扩展带宽。矩形贴片尺寸为38 mm×38 mm,天线高度为14.7 mm。测试结果表明该天线在实现宽带工作的同时具有良好的圆极化特性,同时满足反射系数S11≤-10 d B和轴比AR≤6 d B的有效带宽为22.3%。
[Abstract]:A S-band circularly polarized microstrip antenna is proposed, in which circular polarization radiation is realized by tangent square patch, and the axial ratio is improved by using differential feed to suppress high order mode. The rectangular patch size is 38 mm 脳 38 mm and the antenna height is 14.7 mm. The test results show that the antenna has good circular polarization characteristics while realizing broadband operation. The effective bandwidth satisfying the reflection coefficient S11 鈮，
