Abstract:
The presented research aims to analyze in detail the characteristics of
broadband matching antennas specifically designed for 5G mobile
communications applications, with an emphasis on innovative composite
materials. The study focuses on a compact planar loop antenna designed for
use on smartphones, covering the LTE/WWAN frequency bands
824 to 960 MHz, 1,710 to 2,690 MHz, and 3,300 to 3,600 MHz for full
coverage of modern 5G networks. Experimental and numerical methods are
used to broadly analyze the frequency range associated with 5G networks.
The features of the use of composite materials in the implementation of
antenna devices in 5G technologies are noted. A broadband matching circuit
(BMC) with elements with lumped parameters and a reduced sensitivity
invariant has been synthesized. A 3D model of the adaptive selective surface
controller (SSC) was developed using CST Studio. The study results
highlight the benefits of new composite materials in improving the
performance of 5G antennas. This research makes a significant contribution
to the development of 5G technologies by optimizing antenna design for
efficient data transmission in modern mobile networks and can be a valuable
resource for engineers and designers working in this field.
