Abstrak

Antena mikrostrip patch berbentuk persegi untuk aplikasi synthetic aperture radar pada pita X telah dirancang dan disimulasikan menggunakan teknik pencatuan proximity coupling. Pada bagian tengah patch ditambahkan slot berbentuk “H” untuk menghasilkan bandwidth lebar. Studi parameter dilakukan dengan mengubah parameter fisik antena untuk mengetahui pengaruhnya terhadap kinerja antena. Karakterisasi antena juga dilakukan dengan membandingkan rancangan antena mikrostrip tanpa slot dan dengan slot terhadap antena mikrostrip konvensional. Dimensi akhir rancangan antena mikrostrip dengan H-slot adalah 11,1mm mm. Hasil simulasi menunjukkan bahwa penambahan slot pada antena yang diajukan menghasilkan bandwith fraksional sebesar 34,23% pada rentang frekuensi 7,95GHz sampai 11,23GHz dan gain sebesar 3,57dB pada frekuensi 9,4GHz.

Kata Kunci: Synthetic Aperture Radar (SAR), Antena Mikrostrip, H-Slot, Proximity Coupling
