Abstract

Due to the advancement of telecommunication platform, users are now demanding high performance application. Propagation models play a vital role in the characterization and design of wireless and mobile communications networks. However, if they are utilized in a different environment than the one they were formulated for, propagation path-loss models may produce unacceptable deviation in predictions. Nowadays every mobile service provider continues to build a telecommunications tower with little regard for its impact on the area function. This paper presents the cellular network planning in the district of Bukit Raya, Pekanbaru. From the field survey, there are found sixty-two (62) cell sites. This number is extremely large compared to the calculated one. From the theory, only twenty-five (25) cell sites are required. Thus, it was found inappropriate deployment cell sites.

Abstract

Nowadays, most antenna researchers over the world are focusing on the design of the antenna for the fifth generation (5G) application (indoor and outdoor). High intensive research on 60 GHz antenna for high data rate indoor communication is becoming a trending topic. The high propagation loss at this band is the most challenging. The antenna needs to have higher gain to overcome the loss. Such antenna designs have been proposed recently. This paper, a new MIMO 2x4 patch rectangular antenna operating at 60 GHz is designed for Wi-Gig application. The rectangular patch antenna has 1.75 mm x 1.54 mm of size, printed on Rogers Duroid RT 5880 substrate, the dielectric constant of 2.20 and loss tangent of 0,0009. The antenna was designed and simulated using CST simulation software. The simulated return loss showed a very consistent characteristic. The return loss reached −30 dB at 60 GHz. The broad bandwidth obtained is 4.3 GHz concerning -10 dB. The omnidirectional radiation pattern with 13.4 dBi of gain is obtained. This antenna meets the Wi-Gig requirement.

Abstract

In this paper, a compact design of transparent rectangular microstrip antenna with a slotted ground plane has been designed and evaluated to support Intelligent Transportation System (ITS). The proposed antenna consists of a single element using transparent conductive film AgHT-4 layered on a plain glass substrate, fed by a single 50 Ω SMA port. The antenna is working on 5.9 GHz based on IEEE 802.11p for Wireless Access in Vehicular Environment (WAVE) Standard. The design concept is to have arc shape slot out of the ground plane of a microstrip patch antenna to enable wideband frequency. The proposed antenna provides ultra wide impedance bandwidth around 750 MHz (5.48-6.23 GHz) at a center frequency of 5.9 GHz. The proposed transparent antenna has a directivity gain of 6.266 dBi.

Abstract

Energy consumption is one of the most important, for it is necessary to control the use of home lighting as needed. Monitoring is important, in order to know the quality of electricity supply in the system, identifying disruption events, and to calculate the amount of electrical energy consumption periodically. To achieve the objectives mentioned above, two schemes for home control and monitoring the electrical quantities in real-time have been developed. The first scheme presents Bluetooth based home control. It uses an HC-05 Bluetooth module and Bluetooth Controller mobile application for switching on / off the appliances. Relay and LEDs are used as loads to demonstrate the working of the system. This system is based on Arduino Uno microcontroller board. Arduino Integrated Development Environment (IDE) is used for developing the necessary software. The second scheme uses the current sensor ACS712-20A for monitoring of voltage, current, and energy consumption. The measurement results include voltage, current, power, and the amount of energy consumption that is displayed by LCD 16*2.

Abstract

This paper presents a dual-band antenna for the 5G system communication device. The MIMO antenna can potentially boost the capacity and transmission rates to a new level in a communication system. The MIMO 1x4 elliptic circular patch is designed at 24 GHz and 27.8 GHz. From the simulated S11 results, a single patch antenna provides -16.364 dB at 24 GHz and -35.44 dB at 27.86 GHz. While for the MIMO 1x4 patch, the simulated S11 of -15.563 dB and -21.889 dB are achieved at both 24 GHz and 27.8 GHz, respectively. It has a gain value of 9.04 dBi at the 24 GHz and a gain value of 6.56 dBi at the 27.8 GHz. These gains are higher than the gain obtained with a single element.

Abstract

This paper creates a compact design of a 4×4 butler matrix integrated with an array of antenna elements at 38 GHz frequency. The antenna simulation performance is acceptable, approaching the ideal one. The butler matrix can generate four beams through the output port directly. Each input port 1, 2, 3, and 4 has beam direction, which is 42°, -19°, 19°, and -42°, respectively. The phase difference between output ports of the butler matrix is approaching 45° and 135°. Besides, antenna patch simulation has a good performance. The results are still acceptable after combining the butler matrix and four linear array antenna.

Abstract

One communication medium that is well-known for its outstanding and reliable performance is fiber optic. A social example of its application is the Fiber to the Home (FTTH) network. The goal of this study is to evaluate the signal quality of the customer base method and the branching method, two FTTH-building techniques based on the PT.PLN Icon Plus standards, in order to identify the most practical approach for use in the Air Hitam 2 cluster. Two scenarios were used in this study at the Fiber Access Terminal (FAT) with 1:16 and 1:8 splitters. The fiber optic cable path design findings demonstrate that the branching approach is a wise decision, utilizing optical fiber cables for a total of 9 Km, with the greatest cable distance being 2.5 Km from the Optical Line Terminal (OLT) to the end FAT. According to theory, in the 1:16 splitter situation and the 1:8 splitter scenario, the optical power received by the Optical Network Terminal (ONT) is -19.13 dBm and -16.03 dBm, respectively, with an OLT transmit power of 3 dBm. For these cases, the simulation results are -17.98 dBm and -20.27 dBm. Additionally, the budget value for the rising time reaches 0.253 ns. The bit error rate values in the 1:16 and 1:8 splitter scenarios are 3.157 × 10-10, and 1.63507 × 10-28, respectively, while the Q factor values are 6.18233 and 11.014, respectively. Based on theory and simulation, these findings suggest that the branching strategy can deliver good performance.

Namun, selama pengukuran, RF amplifier memberikan redaman akibat pengaruh penyolderan, short circuit, dan electro statis discharge. Untuk parameter terukur lainnya memenuhi persyaratan standar. Hal ini menunjukkan realisasi microstrip RF amplifier untuk frekuensi tinggi memiliki tingkat keberhasilan yang rendah.Kata kunci: radar pantai, penguat daya, matching stub, mikrostrip ABSTRACTIndonesia is an archipelagic country that needs to monitor its islands. For the independence of coastal radar technology, the need for low cost RF amplifiers is a must.This paper presents simulation and realization of microstrip RF amplifier used RT/Duroid 5580 and matching stub technique worked at 9.3 GHz. This matching technique is effective for high frequency and to match the impedance with imaginer value. The active component of MGF2407A was chosen with DC fixed bias configuration. From simulation, the proposed RF amplifier has gain of 10.318 dB, S11 of -26 dB and S22 of -28 dB with P1dB compression at 11 dBm. However, during the measurement, the RF amplifier provides attenuation due to soldering, short circuit, and electro statis discharge effects. For other measured parameters met the standard requirements. This demonstrates the low success rate of realizing microstrip RF amplifiers for high frequencies.Keywords: coastal radar, power amplifier, matching stub, microstrip

Abstract

The maritime radar is a mobile station used by ships to cover large areas in Indonesian waters. Maritime radar is used to monitor Indonesia's marine waters. One of the maritime radar subsystems is the antenna. The antenna emits the electromagnetic waves into the air to detect an object. In this study, a 1 × 4 circular patch array microstrip antenna is proposed. This antenna is applied to maritime radar working in the frequency range of 2.2 – 4.2 GHz that are allocated by the Ministry of Communication and Information of the Republic of Indonesia. From the simulation results, the proposed antenna provides a return loss of -66.29 dB, and a gain of 7.14 dB at 3.2 GHz.
