Abstract

In this research, a 4x4 butler matrix for wideband-radar application with frequency range in S- Band (operation frequency at 3 GHz) was designed with 4 hybrid coupler and 2 crossover coupler in it. Using electromagnetic band gap (EBG) technique to increase the bandwidth by put the perforated structures (holes) at the ground plane. The research results (modelling by software application)show the design of butler matrix with characteristics of the bandwidth more than 500 MHz. In addition, the value of bandwidth enhancement is up to 259 %.

Abstract

Perancangan dan realisasi antena mikrostrip dengan bentuk rectangular yang dioptimasi menggunakan metode parasitic untuk ultra wideband pada frekuensi kerja 1800 MHz telah dipaparkan dalam penelitian ini. Metode parasitic bertujuan untuk memperlebar bandwidth dan meningkatkan nilai gain dari antena yang dirancang. Dari hasil pengukuran antena rectangular dengan metode parasitik diperoleh nilai return loss sebesar -12 dB, VSWR sebesar 1.679 pada frekuensi 1800 MHz, dan dari hasil yang diperoleh dari proses pengukuran, antena yang diusulkan menghasilkan frekuensi triple band, yaitu pada frekuensi 1815 MHz, 1935 MHz, dan 2060 MHz dengan bandwidth masing-masing 2.4%, 2.8% dan 4.36%.
