Abstract

RLSA antennas were suggested by several researches as Wi-Fi antennas in addition to panel antennas. Therefore, this paper researched the possibility of this suggestion. We used the size of an available in market 16 dBi panel antenna (225 mm2) as the size for our developed RLSA antenna. Based on this size, we developed 60 RLSA models using extreme beamsquint technique and simulated them. We then chose a best model with a best performance. The best model was then fabricated and measured. The simulation and measurement results show that the developed RLSA antenna has better performance compared to the 16 dBi panel antenna in term of gain (0.25 dB higher) and bandwidth (570 MHz wider). The RLSA antenna also tested as antenna for a Wi-Fi device and it showed good performance.

Abstract

Salah satu pemanfaatan komunikasi satelit adalah penggunaan teknologi VSAT pada televisi berbayar menggunakan frekuensi C-band (4 GHz - 6 GHz) dan Ku-band (11 GHz - 14 GHz). Penggunaan frekuensi ini tentunya sangat dipengaruhi oleh redaman hujan. Untuk itu diperlukan perancangan dan pengukuran untuk mendapatkan pengaruh redaman hujan terhadap propagasi sinyal satelit. Pada penelitian ini terbatas pada pengukuran sinyal satelit untuk kanal C-band pada Wilayah Pekanbaru. Hasil data pengukuran kemudian dilakukan pemodelan distribusi data untuk mengetahui karakteristik data penerimaan sinyal satelit untuk kanal C-band. Berdasarkan hasil pemodelan data pengukuran sinyal satelit diperoleh bahwa data pengukuran terdistribusi rician dengan MSE C-band = 0,056052057
