Abstract

In this study, the authors implement an application Spectrum Analyzer used to examine the frequency response of the human voice. This application begins with making the function of the Fast Fourier Transform (FFT), which calculates the value of the amplitude of a wave file. Then the manufacture equalizer and normalization adjusts the value of the highest amplitude of each spectrum to be more easily studied. Spectrum Analyzer application is built using MATLAB programming language. From the test results, the human voice is in the frequency range of 300 -3400 Hz and a human voice shrill has higher frequencies then bass, By using sound recorder application that already include in the operation of windows, the audio signal will be at the input. The audio signal that we will process here is the type of audio signal stereo. Stereo signals having a phase of R and L which produces the dominant voice on the left or right.  Keywords : Fast Fourier Transform (FFT), the audio signal, spectrum analyzer

Abstract

Along with the development of fast wireless technology, car to car communication (C2C) has been widely used in communication between vehicles for internet access and safe driving control. During the last few years, the design of antennas using transparent materials has attracted the interest of researchers. This is due to the low thickness and light structure of transparent materials compared to conventional designs. In this study, the transparent antenna based on LTE technology for C2C communication is developed. This antenna works at 1.8 GHz with return loss of -27.98 dB. The antenna simulation was performed using CST Microwave Studio. Keywords – Transparent antenna, LTE technology, C2C

Abstract

The development of communication technology was started from first generation (1G) to fourth generation (4G), which each new generation always comes with a significant increase in performance. With the increasing of wireless mobile devices and services in the future, there are still some problems and challenges that can not be accommodated even by 4G, such as high data rates, area coverage, and low energy consumption. The 5G (Five Generation) technology presents to solve problems and the need to improve network efficiency and capacity, improved data rate with better coverage at lower power consumption. This research will design a planar array microstrip antenna, MIMO (Multiple Input Multiple Output) 2x2, which works at a frequency of 37 GHz using CST (Computer Simulation Technology) Microwave Studio software. The antenna was designed by using RT-duroid 5880 substrate with a thickness of 0.508 mm. This design uses the technique of Microstrip Line/T-junction consisting of 4 elements. The simulation results obtained for 4 elements array are the return loss of -28.483 dB, the bandwidth of 2,12 GHz, VSWR (Voltage Standing Wave Ratio) ≤ 1,078 and gain ≥ 11,8 dBi, The results obtained by MIMO 2x2 antenna are the return loss of -26,767 dB, the bandwidth of 2,12 GHz, VSWR ≤ 1,096 and gain ≥ 18,7 dBi.

Abstract

LTE and EGSM frequency spectrum in Indonesia are located on adjacent frequency channel. This could potentially cause interference among the systems. This study focuses on the analysis of potential interference between downlink LTE (LTE base station as an interferer) versus uplink EGSM (EGSM base station as a victim of interference). This interference could potentially lower the quality of the signal reception on the EGSM base station. In this study, interference between LTE and EGSM on 800 MHz frequency band will be analysed by using SEAMCAT simulation software. From the simulation’s results obtained, the interference of both systems is eliminated by adding the guard band. The guard band distance of 4.5 km for URBAN environment and the distance of 5.5 km for SUB URBAN provide the highest C/I ≥ 12 dB, respectively.Key words: LTE, E-GSM, guard band, interference, SEAMCAT.

Abstract

Currently, research on MIMO microstrip antennas to support fifth generation (5G) technology is increasing. This is because high data rate is required. A 28 GHz frequency is one of the mobile allocation frequencies approved by the Federal Communication Commission (FCC). In this research, Multiple Input Multiple Output (MIMO) 8x8 smartphone antenna working on 28 GHz using Computer Simulation Technology (CST) Microwave Studio simulation software is designed. The antenna is designed with 4 layers of the same substrate using aperture coupled technique. The aperture coupled technique allows the antenna to generate large bandwidth. Based on simulation result data, This antenna gives the result of parameter simulation values such as bandwidth impedance 2.38 GHz (8.5%), return loss -45.912 dB, Voltage Standing Wave Ratio (VSWR) 1.01 and gain 12.5 dB at 28 GHz. The design of antenna is expected to be applied at mobile smartphones and work on millimeterwave mobile communications systems in the future.Keywords: MIMO, Aperture Coupled, Milimeterwave
