Abstract

Pada penelitian ini telah dilakukan perancangan, simulasi, dan realisasi antena mikrostrip array dengan catuan proximity coupling untuk aplikasi radio altimeter. Penentuan nilai dimensi antena dilakukan dengan menggunakan rumus-rumus antena mikrostrip. Nilai-nilai dimensi yang telah diperoleh kemudian disimulasikan dengan simulator elektromagnetik untuk memperoleh performansi yang dihasilkan. Selain itu, proses simulasi juga digunakan untuk mengoptimasi desain antena. Antena yang dirancang mampu bekerja pada frekuensi 4,3 GHz, dengan return loss< -10 dB, VSWR < 2, bandwidth 100 MHz, gain ≥ 9,25 dBi, pola radiasi unidirectional, dan polarisasi linier. Substrat yang digunakan adalah Rogers RT5880 yang memiliki permitivitas relatif sebesar 2,2 dan ketebalan sebesar 1.57 mm. Antena yang terealisasi bekerja pada frekuensi tengah 4,3 GHz yang menghasilkan VSWR 1,005, polarisasi elips, gain 13,46 dB, pola radiasi unidirectional, impedansi 50,113 - j228,123 mOhm, return loss -51,890 dB, dan effective bandwidth 286 MHz (4,175-4,461 MHz).

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
