Recent advances in satellite to land mobile terminal services and technologies, which utilize high frequencies with directional antennas, have made the design of an appropriate model for land mobile satellite (LMS) channels a necessity. This paper presents LMS channel model at Ku-band with features that enhance accuracy, comprehensiveness, and reliability. The effect of satellite tracking loss at different mobile terminal speeds is considered for directional mobile antenna systems, a reliable tropospheric scintillation model for an LMS scenario at tropical and temperate regions is presented, and finally a new quality indicator module for different modulation and coding schemes is included. The proposedextended LMS channel (ELMSC)model is designed based on actual experimental measurements and can be applied to narrow- and wide-band signals at different regions and at different speeds and multichannel states. The proposed model exhibits lower root mean square error (RMSE) and significant performance observation compared with the conventional model in terms of the signal fluctuations, fade depth, signal-to-noise ratio (SNR), and quality indicators accompanied for several transmission schemes.

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.
