Development of mobile networks requires the simultaneous use of multiple frequency bands. Therefore, development of solutions based on multi-band broadband co-located antenna arrays is becoming increasingly important. The current trend in data network modernization involves the transition to 5G standards, which requires the integration of new radiating structures into existing antenna devices. One possible solution is the addition of an external antenna module specifically designed for operation at 5G frequencies. An alternative approach is the development of frequency-selective antennas, which are capable of transmitting radio waves with minimal distortion and loss, which is critical for high-speed data transmission.

The objective of the article is to analyze modern approaches to the design of multi-frequency broadband antenna systems for 5G/6G cellular stations.

Modern approaches using elements with overlapping frequency bands, combined structures with multi-band elements, materials, and geometric structures with frequency selectivity have been considered. Particular attention is given to methods for combining high- and low-frequency arrays, with an emphasis on creating emitters with minimal interference with elements in other frequency ranges. It has been shown that the use of metamaterials, perforated structures, and specialized geometries minimizes the shielding effect of low-frequency elements and ensures stable signal transmission in the high-frequency ranges of multi-frequency arrays.

The results of this review can be useful in the design of antennas for modern cellular base stations.
