Abstract

ABSTRAKRadio Detection and Ranging (RADAR) merupakan teknologi yang berfungsi untuk mendeteksi, mengukur jarak dan memetakan objek. Salah satu jenis sistem radar adalah sistem radar cuaca yang mempunyai frekuensi C band dengan rentang 5.250 – 5.725 GHz. Komponen utama dalam sistem radar adalah antena. Antena mikrostrip memiliki ukuran kecil, tipis dan mudah diintegrasikan. Namun memiliki masalah bandwidth yang rendah yaitu sebesar 3-5%. Untuk meningkatkan bandwidth antena mikrostrip ini digunakan metode multilayer parasitik. Pada penelitian ini berhasil diperoleh peningkatan bandwidth pada hasil simulasi sebesar 7.1%. Sedangkan setelah realisasi diperoleh peningkatan bandwidth sebesar 39.6%. Pada hasil realisasi antena mikrostrip multilayer parasitik pada frekuensi C band radar cuaca diperoleh hasil pengukuran band frekuensi 5.187 – 5.912 GHz, bandwidth 725.8 MHz, gain 6.99 dB dan pola radiasi unidireksional.Kata kunci: Antena Mikrostrip, C Band, Multilayer, Parasitik, Radar Cuaca ABSTRACTRadio Detection and Ranging (RADAR) is a technology that functions to detect, measure distance and map objects.

气象雷达 C 波段频率的寄生多层微带天线

放射性探测和雷达是一种探测、测量距离和绘制物体地图的技术。其中一种雷达系统是天气雷达系统，其频率为C波段，射程为5250 - 5725千兆赫。雷达系统的主要成分是天线。微带天线很小，很小，很容易整合。但带宽的问题很低，是3-5%。为了增加微带天线的带宽，采用了多层寄生虫的方法。据研究，模拟结果的带宽增加了7.1%。然而，在认识到后，带宽增加了39.6%。在C波段频率C波段的多层微带实现的结果中，气象雷达波段的波段测量结果为5,187—5,912 GHz，带宽725.8 MHz，增益6.99 dB和unidirect辐射模式。关键字:微条状天线、C波段、多层、奇异雷达、气象雷达的探测和跟踪(雷达)是探测、测量距离和对象地图功能的技术。一种雷达系统是一种天气雷达系统，它有一个C波段的频率为5,250 - 5,725千兆赫。雷达系统的主要对照组是天线。微带天线是很小的，很容易整合。悬吊，带宽低3-5%。增加触角的带宽，寄生虫的多层方法被使用。在这项研究中，带宽的增长在7.1%的比率上取得了成功。在实现后的同时，39.6%的带宽被纳入。在C波段天气雷达频率的确定下，频率频率乐队5,187 - 5,912 GHz，带宽725.8 MHz，增益6.99 dB和unidirect模式被证实。微带天线，C波段，多层，寄生虫，气象雷达
