Abstract

In this paper, design and realization of FIR filter with a bandwidth of 40 MHz at 50-90 MHz frequency has been proposed. The design was destined to be implemented on the Inter Satellite Links (ISL). This kind of filter had been selected due to a need in linear phase responseon the ISL data communication. Equiripple method was used to design the filter becauseof its reliability in minimizing the magnitude errors. The design of this FIR filter was conducted with theoretical calculation and simulation using the R2012b Matlab. For the implementation, FPGA was used with a VHDL as the programming language with a help of Xilinx ISE Design Suite 14.5. Simulation results in Matlab and Simulink indicated that the filter design could be well implemented on ISL at frequency of 50 MHz - 90 MHz with stopband of 60 db. The phase responseresult of the realized design is quite linear so that the filter is suitable for data communication on the ISL.

Abstract

In this paper, the microstrip planar fourtear antenna that operate at frequency range 2300 – 2500 MHz was investigated, Some applications suitable to operate in this frequency are WiMAX at 2.3 and 2.5 GHz and WLAN at 2.4 GHz. Simulations performed with the aid of Finite Element Emthod (FEM) based software which can calculte and comply the appropriate design to be able to operate at the desired working frequency. The analyzed parameters include : SWR, impedance, return loss, radiation patterns, gain, and polarization. From the measurement, bandwidth obtained is equal to 7.69% in the frequency range of 2318,250-2500 MHz in VSWR < 2. Radiation pattern measurement was unidirectional and the polarization was elliptical.

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

We analyze the interaction of microwave and optical electric field in a microwave polarization detector based on photonic technology for Electromagnetic Compatibility (EMC) measurement. The detector consists of two orthogonal optical waveguides and patch antennas embedded with two orthogonal gaps fabricated on an Electro-Optic (EO) crystal. Wireless microwave signals can be received, separated and converted directly to lightwave signals through optical modulation using the proposed detector. This detector operates with no external power supply and with low microwave distortion. Microwave polarization can be identified using the proposed interface. In addition, it enables us to measure the magnitude and phase of the wireless signal simultaneously. The analysis of the device was done and presented at the operation frequency of 26 GHz. The proposed interface can be applied for EMC measurement through the radio-over-fiber link.

Abstract

Telah dilakukan perhitungan nilai ketidakpastian pengukuran pada karakteristik material magnet permanen menggunakan alat ukur Permagraph Magnet Physik Germany. Karakteristik magnet yang diukur adalah induksi remanen, Br (kG), gaya koersifitas induksi, HcB (kOe), gaya koersifitas polarisasi, HcJ (kOe), kuat medan remanen kiri, Hknee (kOe), produk energi maksimum, BHmax (MGOe), kuat medan produk energi maksimum, Ha (kOe), magnetik fluks, Ba (kG), kuat medan maksimum, Hmax (kOe). Sebelum menentukan nilai ketidakpastian dengan permagraph terlebih dahulu ditentukan nilai ketidakpastian dengan alat penunjang, yaitu jangka sorong dan neraca analitik. Selanjutnya akan didapat nilai ketidakpastian gabungan. Metoda ketidakpastian yang digunakan adalah dengan cara statistik dan berlaku hanya untuk serangkaian observasi. Penentuan nilai ketidakpastian dilakukan dengan cara melakukan pengukuran yang berulang sebanyak sepuluh kali terhadap sample yang sama. Metoda ini mengacu kepada ISO GUM dengan menggunakan evaluasi tipe A. Nilai ketidakpastian yang didapat untuk pengukuran dengan jangka sorong adalah ±0,0329 cm, neraca analitik ±0,0528 gr, dan untuk karakteristik magnet Br ±0,0648 kG, HcB ±0,0632 kOe, HcJ ±0,0628 kOe, Hknee ±0,0643 kOe, BHmax ±0,0631 MGOe, Ha ±0,1213 kOe, Ba ±0,0664 kG,Hmax ±0,0627 kOe.
