Abstract
The relevance of the topic is to develop cellular networks, which, on the one hand, requires the development of antenna devices that provide the required communication range, and on the other hand, imposes restrictions on the linear dimensions of emitters while maintaining the requirements for ease of manufacture and reliability of operation, taking into account adverse weather conditions. With the transition to next-generation communication standards, there is an increasing demand for antenna systems capable of operating over a wide frequency range and providing a stable signal level under high subscriber density. Of particular importance is the development of antenna arrays that allow the formation of specified radiation patterns and ensure uniform coverage of the serviced area.
The goal is to develop a small-sized antenna array with the required electrical characteristics. Antenna elements should be distinguished by manufacturability. The finite element method (FEM) and the finite difference method in the time domain (FDTD) are used as numerical methods for calculating the electrical characteristics of the antenna. The gradient optimization method is used to solve the problem of reducing the linear dimensions of the antenna element while maintaining directional and range properties.
The result of the study is a full-size experimental sample of a linear antenna array of a cellular base station. Its design and characteristics are substantiated in this work.
Novelty: description of the method of a new approach to the manufacture of an antenna element, which differs from existing ones by using a special underlying insert under each element of the antenna array.
The practical significance of the results of scientific research lies in the development of an antenna array with a distortion-free directional diagram in the frequency range of 1710‒2700 MHz and a gain of at least 15 dB.
