Karakterisasi Antena Mikrostrip Slot Bowtie pada Frekuensi 2,4 GHz
Sari
Abstrak Telah dihasilkan rancangan dan hasil simulasi antena mikrostrip slot bowtie yang dapat bekerja pada frekuensi 2,4 GHz untuk sistem komunikasi wireless. Hasil karakterisasi antena diperoleh dengan menggunakan Vector Network Analyser (VNA). Dalam penelitian ini didesain 3 buah antena slot double bowtie dengan variasi lebar widthline. Hal ini mengakibatkan perubahan slot line yang sebanding dengan hasil nilai impedansi masukan. Semakin kecil lebar slot line, maka semakin kecil impedansi masukan yang dihasilkan. Pengukuran terbaik parameter antena diperoleh nilai VSWR 1,3, return loss -16,48 dB, dan impedansi masukan 53,6 ?. Hasil karakterisasi yang diperoleh dari ketiga antena secara umum telah memenuhi syarat untuk dapat digunakan pada sistem komunikasi wireless sesuai dengan standar industri WLAN IEEE 802.11, dimana nilai karakterisasi VSWR ? 2 dan nilai return loss ? -9,54 dB.
