ABSTRAK Radio 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.

One type of radar system is a weather radar system that has a C band frequency with a range of 5,250 - 5,725 GHz. The main component in a radar system is the antenna. Microstrip antennas are small, thin and easy to integrate. However, it has a low bandwidth problem of 3-5%. To increase the bandwidth of this microstrip antenna, the parasitic multilayer method is used. In this study, an increase in bandwidth was successfully obtained in simulation results of 7.1%. Meanwhile, after realization, an increase in bandwidth of 39.6% was obtained. In the realization of the parasitic multilayer microstrip antenna at the C band frequency of the weather radar, the measurement results of the frequency band 5.187 - 5.912 GHz, bandwidth 725.8 MHz, gain 6.99 dB and unidirectional radiation pattern were obtained.
