Simulation and Design of a Small-Sized Pentagon Broadband Antenna for 5G Connectivity

This paper focuses on the design and modeling of a pentagonal antenna for 5G networks that meets a number of requirements required for high-frequency devices. The study focuses on the key characteristics of 5G antennas, such as wide bandwidth, compactness, high efficiency and low loss, as well as omnidirectionality, which can be useful in densely built-up areas and high device concentrations. The pentagonal antenna shape is considered as an optimal solution, since its geometry contributes to improved matching with transmission lines, compactness and increased bandwidth. The design parameters, such as frequency range (24-40 GHz), impedance matching and material selection are described in the paper. Software packages including CST Microwave Studio, HFSS and MATLAB are used to model the antenna. This allows obtaining three-dimensional characteristics, estimating gains and radiation patterns. The simulation results demonstrate the distribution and efficiency of radiation at 25 and 28 GHz, optimization of design parameters and the possibility of using the pentagonal antenna in devices for 5G networks requiring high throughput and reliable connection.
