Публікація Особливості забезпечення електромагнітної сумісності радіопристроїв малого радіусу дії(ХНУРЕ, 2023) Завгородній, А. С.Considered issues of ensuring the reliable operation of short-range radioelectronic devices in conditions of interference. It is shown that the analysis of the electromagnetic compatibility of a short-range device must be carried out separately for indoor radio-electronic devices and outdoor devices, since the propagation of radio waves indoors differs from propagation in free space.Публікація Підсилювач сигналу стільникового зв’язку (GSM репітер)(ХНУРЕ, 2023) Варейчук, В. Е.This work is devoted to the topic of cellular signal amplifiers. They serve to strengthen the signal and locally expand the network coverage area. In this work bandpass, filters for the reception band of the reception path of GSM standards (890 - 915 MHz; 1710 - 1785 MHz) are designed.Публікація Вплив висот антен на енергоефективність канала зв’язку(ХНУРЕ, 2023) Савенко, С. О.This work is devoted to assessing the effect of antenna heights on the desired radiated signal power while maintaining the range of the communication channel. The optimal choice of antenna height for increasing the efficiency of communication systems and reducing power consumption is considered. The Okumura-Khata model was used as the basis of the calculation. The obtained results make it possible to estimate the energy efficiency of the communication system that can be obtained by changing the height of the antennas. We studied the optimal value of the antenna mast, which minimizes the total costs for the construction of such a channel and its further operation.Публікація Система моніторингу транспортування цінних вантажів(ХНУРЕ, 2023) Скорий, Р. Г.At the beginning of the third decade of the 21st century, radical changes are taking place in the content and character of international relations and world politics. The prerequisites for the formation of a multipolar world order are emerging, as evidenced by the emergence of new centers of power and influence on the development of the international economy. Despite all the difficulties and problems, global economic ties are being built, integration associations of the USA, the collective west and Ukraine are being created. At the same time, the question of organizing satellite systems for monitoring the transportation of valuable cargo is acute.Публікація Оптимізація роботи малопотужних сонячних панелей в умовах нестабільного електропостачання(ХНУРЕ, 2023) Верягін, В. В.The solar energy development has made it possible to install solar panels even at home. This can be justified especially in the power outages event. But the low-power solar panels operation in unsuitable conditions has some features. Firstly, there may not be a completely open sky in an unsuitable place. Secondly, the low solar panel output makes to take into account the energy losses for its control. These theses are about these and other features of the operation of a low-power solar panel.Публікація Калібратор магнітометрів змінних полів(ХНУРЕ, 2023) Луб’янко, А. О.The development and research of a calibrator for calibration of magnetometers is describedПублікація Основні підходи використання технології на основі кількох входів та кількох виходів(ХНУРЕ, 2023) Костень, Т. Б.Information protection in all spheres of activity is becoming more relevant now. The growth of users and the volume of processed information within the information field, which must be protected, has significantly increased. One of the technologies that allows you to solve the problem of capturing large amounts of information without losing bandwidth in the network is a technology with multiple inputs and multiple outputs Multiple Input Multiple Output (MIMO). MIMO is a method of spatial signal coding that allows to increase the bandwidth of the channel, in which the transmitting side uses two or more antennas and the same number of antennas for the receiving side.Публікація Моделювання антенного фактора рамкових антен(ХНУРЕ, 2023) Василенко, Д.
