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

Education and culture are two aspects that are closely related to each other and have a significant influence on each other. Both support each other and cannot be separated in shaping people's lives. Education has a strategic role in every cultured society. To maintain the sustainability of a culture, education can be used as a means to introduce, understand and appreciate the culture of a society to the younger generation. Vice versa, culture plays a role in shaping education for a society by providing values, beliefs and norms that form the basis of the educational objectives. Therefore, education cannot be separated from culture and society as the owner of that culture.

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.

Makalah ini menyajikan simulasi dan realisasi microstrip RF amplifier menggunakan RT/Duroid 5580 dan teknik matching stub pada frekuensi 9,3 GHz. Teknik ini merupakan yang efektif untuk frekuensi tinggi dan mencocokkan impedansi dengan nilai imajiner. Komponen aktif MGF2407A dipilih dengan konfigurasi DC fixed bias. Dari hasil simulasi, RF amplifier yang diusulkan memiliki gain sebesar 10,318 dB, S11 sebesar -26 dB dan S22 sebesar -28 dB dengan kompresi P1dB sebesar 11 dBm. 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
