Abstract

In this paper, the design of microstrip BPF (Bandpass Filter) for WiMAX (Worldwide Interoperability for Microwave Access) application has been presented. The frequency band allocations for BWA (Broadband Wireless Access) in Indonesia are 2.3; 3.3 and 5.8 GHz. This microtrip BPF is designed using parallel coupled line in compact form and it has spesific parameter, i.e. 3.35 GHz center frequency, 400 MHz bandwidth, VSWR ≤ 2, -3 dB insertion loss and matching impedance between two port is 50 Ω. The Advanced Design System (ADS) software has been used during simulation and optimization. The simulation results show that return loss S11 and insertion loss S21 are -15.31 dB and -2.2 dB at 3.35 GHz respectively. For the design verification, the prototype of the proposed design wasfabricated and measured.The results of the fabrication approach of simulation results, which have return loss value S11and insertion loss S21 of the proposed microstrip filter are -18.20 dB and -2.91 dB at 3.35 GHz respectively. The result shows that the proposed design can be implemented forWiMAX communication system applications

Abstract

Dalam penelitian ini, dilakukan rekayasa patch fraktal sierpinski dan minkowski dengan cara membedakan geometri fraktal iterasi pertama dan kedua. Analisis multiband dilakukan pada konfigurasi groundplane penuh, dan analisis wideband dilakukan pada konfigurasi groundplane terpotong. Kesimpulan dari penelitian diterapkan pada desain antena ultra-wideband yang sudah ada untuk pembuktian. Hasil penelitian menunjukkan bahwa fraktal sierpinski dan minkowski konvensional bukanlah yang paling optimal untuk bandwidth impedansi keseluruhan. Sifat multiband pada sierpinski maupun minkowski dengan konfigurasi groundplane penuh berkaitan erat dengan luasan geometri yang mengubah lintsan dalam dan luar patch, serta perubahan impedansi antena yang dependen terhadap frekuensi. Hasil pengukuran membuktikan bahwa sifat wideband pada konfigurasi groundplane terpotong berubah signifikan terhadap bentuk geometri dengan penskalaan besar, terutama dalam penurunan return loss. Kata kunci : antena fraktal, multiband, wideband, minkowski, sierpinski
