RANCANG BANGUN ANTENA TRICULA KLOPFENSTEIN UNIDIREKSIONAL UNTUK DAERAH KERJA 300 MHZ-3000 MHZ

ABSTRAKSI: Antena merupakan penyepadan impedansi instrinsik ruang propagasi dengan impedansi saluran radio.Antena Tricula Klopfenstein Unidireksional merupakan antena yang berbasis tiga cula yang disusun oleh dua buah strip/plat yang mempunyai bahanbahan dielektrik secara gradual Klopfenstein.Pada proyek akhir ini dirancang antena berpita lebar yaitu antena Tricula Klopfenstein Unidireksional Untuk Daerah Kerja 300 MHz – 3000 MHz SWR 2,14 dBi, Tanpa Ferit.Dari hasil pengukuran yang dilakukan, diperoleh hasil yang mendekati spesifikasi perancangan yaitu pada frekuensi 1118,1 MHz – 2907,1 MHz VSWR yang didapat Kata Kunci : Kata kunci : Tricula Unidireksional, daerah kerja antenna 300 MHz – 3000 MHzABSTRACT: Antenna is device to match the intrinsic impedance of propagation space and the characteristic impedance of radio channel.Unidirectional Klopfenstein Tricula is the antenna based on three-wire that are arranged of twin wires and plates with dielectric materials. This antenna is built on Klopfenstein gradual matchingIn this final project, wide band antenna was applied. It is Tricula Klopfenstein Unidireksional Antenna for range 300 MHz – 3000 MHz SWR 2.14 dBi, Without Ferrite.From the result, which done of the measurement, commonly the result obtained which close from scheme specifications at frequency of 1118.1 MHz – 2907.1 MHz got VSWR all under 1.5. Radiation pattern unidirectional, polarization close with linear (ellipse), obtained gain 8.184 dBi at frequency of 1650 MHz, 8.125 dBi at frequency of 2400 MHz, and 7.708 dBi at frequency of 2900 MHz.Keyword: Key word : Unidirectional Tricula, 300 MHz – 3000 MHz range frequency
