Abstract

ABSTRAKKebutuhan sistem komunikasi satelit bergerak pada pita Ku sekarang ini mulai berkembang di Indonesia. Ku-band memiliki ketersediaan lebar pita yang besar dan memilikipanjang gelombang yang lebih pendek. Panjang gelombang yang pendek berpengaruh pada dimensi perangkat yang lebih kecil.Pada umumnya antena satelit untuk sistem yang bergerak menggunakan parabola namun penggunaannya pada kendaraanterkendalaberatnya masa keseluruhan sistem sehingga diperlukan sistem kendali motor dengan harga mahal. Oleh karena itu, penggunaan antena mikrostrip dengan metode antena susun (array) menjadi solusi yang dapat memungkinkan kendaraan tetap bergerak dengan baikdengan tetap menjaga kelangsungan hubungan telekomunikasi selama bergerak.Pada penilitian ini, suatu antena mikrostrip penerima dengan menggunakan metode array dengan jumlah patch2x16 yang mampu bekerja pada pita Ku-Band telah dirancang dan direalisasikan. Antena ini bekerja pada frekuensi 11,9 GHz dengan gain sebesar18,69 dB.Kata kunci: komunikasi satelit, Ku-Band, antena mikrostrip, antena mikrostrip array.ABSTRACTNeeds of mobile satellite communication system at Ku Band are currently being widely grown in Indonesia. Ku-band has a large bandwidth availability and has a shorter wavelengt. The short wavelength effect on the smaller device dimensions. In general, satellite antennas for mobile system uses parabolic antenna but if its use on vehicles the obstacle is weighing of the whole system so it takes motor control system with an expensive price. Therefor, the use of microstrip antenna by using antenna array is a solution that can allow the vehicle to keep moving well while maintaining the continuity of telecommunication links during the move. In this research, a microstrip antenna array receiver using the patch number 2x16 are able to work in the Ku-band has been design dan realized. The antenna work at 11.9GHz with a gain 18,69dB.Keywords: satellite communication, Ku-Band, microstrip antenna, array microstrip antenna.

Abstract

Radar has been widely used for various purposes such as monitoring atmospheric precipitation. For that purpose, it gives more accurate results than satellites do. Previous research has developed navigation radar that alters its functions into an atmospheric precipitation monitoring radar. To improve the development of the radar, an antenna system will be developed in this research. The purpose of developing this antenna is to obtain better data reception results. This antenna is a microstrip rectangular array antenna that works on X-band with a frequency of 9.41 GHz. Microstrip antenna is chosen since it has several advantages such as small dimensions and relatively low costs. The designed antenna gain ? 12 dB, bandwidth of 60 MHz, and horizontal polarization. Antenna fabrication produces a microstrip rectangular 16 x 1 array antenna using the mitered bend method at a frequency of 9.4 GHz with a reflection coefficient of -22.8 dB, VSWR of 1.2, gain of 13.21 dB, unidirectional radiation patterns and horizontal polarization.

Abstract

Time Domain Characterization of 1-2 GHz Circular-ended Bowtie Antenna Using Normalizad Impulse Response. Frequency domain analysis is a powerful and compact tool for characterizing the antenna parameters such as gain, radiation pattern and the impedance as a function of frequency. However, if time or space is a major concern, such as in the GPR appication, the time domain analysis would be a very important tool due to their unique capability for determining the echo delay and range profile of target image. In this paper, we will describe the classical theory of system characterization in time domain, and then also propose the mathematical model for characterizing the 1 – 2 GHz circular-ended Bowtie antenna. From the measurement results, we concluded that the implemented Bowtie antenna has good normalized impulse response with very small ringing, so it is suitable for GPR applications.

Abstract

Design and Implementation of 1-2 GHz Stepped Frequency GPR for Buried Metal Detection. In this paper, we describe the design and realization steps of 1 – 2 GHz SFGPR (Stepped Frequency Ground Penetrating Radar) transceiver for metal detection under the ground. Before using prototyped GPR for detecting the metal under the ground, several of calibration processes must be performed, namely phase calibration and monocycle pulse waveform calibration. After completing the calibrations, this prototyped GPR would be ready for detecting a hidden object such as a metal plate 5 cm under the ground in our small test range size 25 cm x 75 cm x 10 cm. From the calibration and detection results, we concluded that the prototyped SFGPR passed the technical specifications of the design and could perform the metal detection under the ground with high SNR.
