PERBAIKAN KARAKTERISTIK RADIASI ANTENA SUSUN MENGGUNAKAN DGS BENTUK SLOT MI
Abstract
ABSTRAK
Pada penelitian ini membahas antena mikrostrip susun dua elemen yang dikembangkan dengan menerapkan Defected Ground Structure (DGS) bentuk Slot MI baris. DGS ini diletakan pada bidang pentanahan dari substrat dengan posisi diantara kedua elemen antena susun. Hal ini dilakukan agar dapat menekan efek coupling yang timbul pada antena susun. Hasil simulasi dan pengukuran dilakukan dengan membandingkan kinerja antena susun patch segi tiga dua elemen tanpa DGS dan antena DGS bentuk slot MI baris. Dimana pada frekuensi 2,004 GHz hasil simulasi nilai kopling antena tanpa DGS sebesar -24,66 dB dan hasil pengukuran nilai kopling antena tanpa DGS sebesar -21,124 dB. Sehingga pada frekuensi 2,004 GHz terjadi penurunan nilai kopling sebesar 3,536 dB. Sedangkan hasil simulasi nilai kopling antena DGS 1x4 bentuk slot MI baris sebesar -26,557 dB dan hasil pengukuran nilai kopling antena DGS 1x4 bentuk slot MI baris sebesar -30,128 dB. Sehingga pada frekuensi 2,004 GHz terjadi perbaikan nilai kopling antena sebesar -3,551 dB. Hasil ini membuktikan bahwa penerapan DGS bentuk slot MI baris ini dapat mereduksi kopling antar elemen yang berdekatan pada antena susun.
Kata kunci: Antena Susun; defected ground structure (DGS); kopling; slot meandered inductor (MI).
