Одним из ключевых рабочих диапазонов для беспроводной связи является диапазон очень высоких частот (ОВЧ). Этот диапазон частот подходит для различных применений, таких как наземная мобильная связь, FM/телевещание, любительская радиосвязь и т. д. Следовательно, важно изучить конструкции антенн, которые подходят для этого диапазона. В данной работе основное внимание уделяется проектированию дипольной складной антенны на частоте 100 МГц. Были проведены моделирование, изготовление и тестирование. В статье представлена новая модель, а также реализация сложенной дипольной антенны, которая оптимизирована для применения в военной технике в диапазоне ОВЧ (30–300 МГц). В предложенной антенне измерены резонансная частота 98 МГц, коэффициент отражения –28 дБ и коэффициент стоячей волны по напряжению (КСВН) 1,07, что полностью соответствует как результатам моделирования, так и теоретическим данным. Кроме того, предлагаемая антенна демонстрирует широкую рабочую полосу пропускания 12 МГц, сохраняя при этом компактность, что позволяет использовать ее в транспортных средствах (~2,9 м). Сочетания улучшенного согласования импеданса, стабильной полосы пропускания и возможности изготовления в полевых условиях являются характеристиками, которые отличают рассматриваемую антенну от традиционных конструкций сложенных диполей, используемых в диапазоне ОВЧ. Проведен сравнительный анализ графиков S11, на которых отображены результаты моделирования и изготовления. Характеристики сложенной дипольной антенны сопоставимы с характеристиками обычной дипольной антенны, и для ее проектирования и оценки можно использовать программное обеспечение HFSS. Проведенные исследования показывают, что результаты моделирования коэффициента отражения для сложенной дипольной антенны хорошо согласуются с полученными данными.

One of the key operating bands for wireless communication is the VHF (Very High Frequency) band. This band accommodates a variety of applications within its operational frequency range, such as Land Mobile, FM/TV Broadcast, amateur radio etc. Consequently, it is essential to explore Antenna designs that are suitable for this band. This paper concentrates on the dipole folded antenna design at 100 MHz frequency. Simulations, fabrication, and testing have been conducted. This paper presents a novel model, along with the implementation of a folded dipole antenna optimized for military vehicular applications in the VHF band (30–300 MHz). The proposed antenna achieved a measured resonant frequency of 98 MHz, a return loss of –28 dB, and a VSWR of 1.07, which closely corresponds with both simulated and theoretical results. Furthermore, the antenna demonstrates a wide operational bandwidth of 12 MHz while maintaining a compact structure suitable for vehicles (~2.9 m). This combination of enhanced impedance matching, stable bandwidth, and field-ready fabrication distinguishes it from traditional folded dipole designs used in the VHF range. We have compared the S11 plots of the simulated results and the fabricated results. The characteristics of a folded dipole antenna are comparable to those of a dipole Antenna, and HFSS software can be utilized to design and assess it. At the conclusion of the investigation, the simulated return loss result for the folded dipole antenna aligns well.
