Однако необходимо оценить потенциальное негативное воздействие электромагнитного излучения устройств этих систем на ткани человека, чтобы обеспечить безопасность здоровья человеческого организма. Представляемое исследование было направлено на оценку степени воздействия электромагнитного излучения микрополосковой антенны на голову человека на частотах миллиметровых волн и улучшение характеристик этой антенны для обеспечения безопасности здоровья человека. В ходе проведения исследования с помощью программного комплекса CST Studio Suite 2021 выполнено следующее: смоделирована микрополосковая антенна, излучающая на частоте 38 ГГц; оценены эффективность и производительность смоделированной антенны для устройств систем 5G; спроектированы и смоделированы слои головы человека для анализа воздействия на нее излучения смоделированной антенны; оценена удельная скорость поглощения энергии излучения антенны каждым слоем головы человека. По результатам исследования предложены и теоретически обоснованы подходы к снижению значения удельной скорости поглощения электромагнитного излучения верхними слоями головы человека. Эти подходы состоят в добавлении в микрополосковую антенну различных материалов в качестве защитных барьеров.</p></abstract><trans-abstract xml:lang="en"><p>5G systems have many interesting advantages, that’s why their popularity around the world is grow ing rapidly. However, it is necessary to evaluate the potential negative impact of electromagnetic radiation from devices of these systems on human tissue in order to ensure the safety of the health of the human body. The present study was aimed at assessing the degree of exposure of the human head to electromagnetic radiation from a microstrip antenna at millimeter wave frequencies and improving the performance of this antenna to ensure human health safety. During the study, using the CST Studio Suite 2021 software package, the following was done: a microstrip antenna emitting at the frequency of 38 GHz was simulated; the efficiency and performance of the simulated antenna for 5G system devices was assessed; the layers of the human head were designed and simulated to analyze the impact of the simulated antenna radiation on it; the absorption specific rate of radiation energy from the simulated antenna by each layer of the human head was estimated. Based on the results of the study, approaches to reducing the SAR value of the human head were proposed and theoretically justified. These approaches consist of adding various materials to the microstrip antenna as protective barriers.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микрополосковая антенна</kwd><kwd>электромагнитные волны</kwd><kwd>удельный коэффициент поглощения</kwd><kwd>голова человека</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microstrip antenna</kwd><kwd>electromagnetic waves</kwd><kwd>specific absorption rate</kwd><kwd>human head</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Yazbek K., Hassan A.
