Abstract

Unmanned aerial vehicle (UAV) in Indonesia is commonly known as Pesawat Udara Nir Awak (PUNA). Data link from aerial observation, required transmitter mounted on the PUNA and components of the constituent is antenna. Antenna must have a small size and light in weight, because the limitation due to the payload capacity. Currently used in the PUNA, is a dipole antenna which still has some weakness, including its susceptibility to the wind (drag effect). So, designing a microstrip antenna will improve the signal transmission performance from PUNA to Ground Control Station (GCS). The microstrip antenna is chosen because this type of antenna has low profile drag, light weight, easy for fabrication and of course low cost. After an antenna design optimization, the antenna placement should be noted to ensure a good transmission. In this research, the microstrip antenna will be operated at 2.35 GHz for video monitoring and the antenna itself will be placed inside the fuselage. Simulated co-site interference will be performed at the operational frequency of data link antenna, which is 900 MHz, with the placement in the upper surface (canopy) of the PUNA. The measurements in the anechoic chamber, showed that the internal fuselage microstrip antenna worked at the frequency of 2.35 GHz with a bandwidth 60 MHz (2.31 GHz up to 2.37 GHz), while the return loss measured at 2.35 GHz is -23.85 dB and the gain of antenna is 3.81 dBi.

Abstract

Wilayah Indonesia merupakan bagian dari Lingkaran Api Pasifik. Ini ditandai dengan banyaknya gunung berapi aktif yang menghiasi kontur wilayah Indonesia dari timur ke barat. Berdasarkan sejarah, rangkaian gunung berapi ini terbukti memiliki peranan penting dalam mempengaruhi iklim dunia. Hal ini masih berlangsung sampai hari ini hingga waktu yang akan datang. Oleh karena itu, pengetahuan yang cukup mendalam mengenai keberadaan rangkaian gunung berapi ini sangatlah penting untuk keberlangsungan hidup masyarakat di sekitar wilayah Indonesia maupun masayarakat dunia. Pemantauan rangkaian gunung berapi ini merupakan tugas yang membutuhkan banyak tenaga dan fasilitas yang memakan biaya besar. Penggunaan pesawat tak berawak (PUNA) menawarkan solusi alternatif untuk pemenuhan tugas ini. Efisiensi dalam melaksanakan pemantauan seperti pengumpulan gambar termal di area sekitar gunung berapi serta pengumpulan data dan gambar yang lebih spesifik dapat dilakukan dengan biaya yang relatif lebih kecil. Hal ini bisa dilakukan karena biaya operasi PUNA yang lebih murah dan mudahnya mengatur sendiri jadwal pemantauan PUNA sesuai dengan kebutuhan. Kata Kunci: PUNA, UAV, Gunung berapi, Gambar termal

Abstract

The variation in the k-factor value significantly influences the performance of unmanned aerial vehicle (UAV) air-to-ground point-to-point line of sight (A2G PTP LOS) communications over a Rician channel at 1,800 MHz using quadrature phase shift keying (QPSK) modulation and orthogonal frequency division multiplexing (OFDM) techniques. The research emphasizes the impact of the k-factor, which quantifies the dominance of the line-of-sight component over multipath scattering. The variation in the k-factor significantly influences UAV A2G PTP LOS communication performance for the empirical model (EM), as it involves precise measurements of the received power level in dBm from UAV to ground control station (GCS) across varying distances and altitudes. We introduce a method to compute the k-factor by assessing the ratio of the line-of-sight signal power to the multipath signal power, thereby enhancing channel modeling accuracy. Empirical analysis shows a strong correlation between bit error rate (BER) and signal-to-noise ratio (SNR) with differing k-factor values; a higher k-factor of 16.3 markedly improves performance, virtually eliminating errors at a 10 dB SNR, while a lower k-factor of 2.39 still shows significant errors at a 30 dB SNR. These results highlight the necessity of optimizing the k-factor in UAV A2G PTP LOS systems to ensure stable and reliable communication under diverse operational conditions.

Abstract

This paper presents an experimental examination of how unmanned aerial vehicle (UAV) airframe materials affect the electromagnetic characteristics of the airborne circularly polarized (CP) payload antenna. This study specifically investigates the received signal from the circularly polarized synthetic aperture radar (CP-SAR) antenna installed within the fuselage of the lapan surveillance UAV (LSU). In the airborne CP-SAR experiment, broadband CP microstrip subarray antennas were used along with LSU series airframe material composites comprising E-glass EW-185 and Carbon C522 Twill. The composite specimens were prepared to have the same size and thickness to minimize variability in the comparative analysis. The experimental study measures the transmission loss using S-parameters. At 5.3 GHz, the E-glass EW-185 fiber composite exhibits a material attenuation of -1.5 dB and a circular depolarization of 0.32 dB. The E-glass EW-185 fiber composite exhibits a material attenuation of -1.5 dB and a circular depolarization of 0.32 dB. In contrast, the Carbon C522 Twill fiber composite demonstrates a significantly higher material attenuation of -31.24 dB and a circular depolarization of 10.70 dB. Additionally, this paper examines the radiation pattern measurements of the CP-SAR antenna at various frequencies, providing a comprehensive analysis of the materials' impact on antenna performance.
