With the development of 5G technologies, there is a growing need to improve antenna systems operating in the VHF band to ensure stable communication in urban environments. The main challenges include reducing the size of antennas, expanding coverage areas, and increasing radiation efficiency, especially in the presence of multipath interference.

The goal of the work is development and optimization of antenna systems that provide high radiation performance and compact dimensions, enabling effective integration into modern mobile networks and IoT systems.

The authors have proposed structural modifications to antenna systems, including the use of spiral radiators, adjustment of arm lengths, and changes in the number of segments. Experimental modeling has confirmed that these antennas exhibit stable radiation patterns, reduced interference levels, and optimized input impedance at operating frequencies. The developed prototypes have demonstrated improved performance across the frequency bands used for mobile communication.

The proposed solutions enable high-quality communication in urban environments, making them suitable for use in 5G and IoT networks. These developments can be implemented in the antenna systems of mobile operators and serve as a foundation for further research in the field of multi-element antennas.
