Simulation of 3600–3800 MHz frequency band antenna for fifth generation mobile communication

The design and modeling of the antenna for frequencies 3600–3800 MHz is presented, for mobile communication of the fifth generation, consisting of two dipoles orthogonally to each other. The dipole consists of a microstrip resonator on one side of the substrate and a power line on the other. The formation of the directivity pattern is achieved due to the emission of a gap in the resonator. The developed antenna provides a gain of at least 5 dBm. Modeling is carried out in the software package Ansys HFSS. The results of the calculation of the directional pattern and VSWR are presented. For additional protection, the antenna was placed in a radio-transparent shelter. Also for this antenna, a power divider and band-pass filter was developed for this frequency range. The main advantages of this antenna are its simplicity in manufacturing, protection from external mechanical influences and low cost.
