【摘要】：提出了一種S波段寬帶圓極化微帶天線。該天線采用切角方形貼片實(shí)現(xiàn)圓極化輻射,利用差分饋電抑制高次模改善軸比,通過貼片上開雙十字槽和增加空氣層擴(kuò)展帶寬。矩形貼片尺寸為38 mm×38 mm,天線高度為14.7 mm。測試結(jié)果表明該天線在實(shí)現(xiàn)寬帶工作的同時(shí)具有良好的圓極化特性,同時(shí)滿足反射系數(shù)S11≤-10 d B和軸比AR≤6 d B的有效帶寬為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，
