Abstract


Pada penelitian ini dirancang antena mikrostrip dengan slot double F, di mana antena ini dapat digunakan untuk perangkat wireless yang bekerja pada frekuensi multiband. Antena mikrostrip double F dirancang dengan simulasi, dipabrikasi dan diukur secara riil. Finite Difference Time Domain (FDTD) digunakan untuk menganalisis karakteristik distribusi arus yang tersebar pada mikrostrip. Nilai parameter terbaik dari hasil simulasi untuk return loss adalah -31,09 dB pada frekuensi 2,4 GHz dan VSWR sebesar 1,057 sedangkan hasil pengukurannya sebesar -32,82 dB pada frekuensi 2,4 GHz dan VSWR sebesar 1,045. Penggunaan slot pada patch antena dan pencatuan proximity yang digunakan meningkatkan bandwidth antena sebesar 48,7% dan gain yang dihasilkan sebesar 5,97 dBi.
