Comprehensive Study on the Design and Optimization of Log-Periodic Antennas for Ultrahigh Frequency Telecommunication Systems

Abstract

The main component of modern wireless telecommunications networks is the log-periodic antenna, which is designed to operate at high frequencies. It meets the requirements of modern high-frequency technologies and provides reliable and efficient data transmission in a given frequency range. The wide range of operating frequencies and high directionality make the log-periodic antenna an ideal choice for modern telecommunication communication systems. The log-periodic antenna is capable of efficiently transmitting signals over long distances and ensuring stable communication in changing radio frequency environments. In this article, we will explore research findings concerning the modeling of electrical parameters and directional characteristics of antennas operating in the ultra-high frequency range. This exploration involves augmenting the quantity of wideband log-periodic antenna elements utilized in wireless communication systems, altering the material composition of such antennas, and varying the operational environment. The process of designing an antenna device using computer software can be divided into the following main stages: problem formulation, structural synthesis, mathematical modeling and analysis of electrical properties, parameter optimization, and analysis of the antenna's radiation pattern. The scientific research was modeled using the MMANA-GAL program within the frequency range of 450-870 MHz. This program facilitates the easy preparation of information for calculations and analysis of results. Both text and graphical modes were utilized for constructing the antenna model and displaying the program's outcomes. © 2024 IEEE.
