Abstract
The antenna is a critical component of the communication system. The antenna is used in wireless communication for signal transmission and reception over long distances. There are numerous sorts of antennas, such as wire antennas, traveling wave antennas, reflector antennas, microstrip antennas, and so on. The application of antennas is determined by the antenna's attributes as well as the frequency range of operation. As a result, it is vital to understand the behavior of antennas over a wide range of operations and select the optimum antenna for the application. The performance parameters of the antenna determines its efficiency. VSWR, Return Loss, Directivity, Bandwidth, and more parameters are available. As a result, one of the primary areas of focus is antenna analysis. In this study, we simulate various antenna types and derive performance parameters such as return loss, directivity, and so on. MATLAB will be used to simulate the antenna at various frequencies. When all of the parameters are taken into account, the analysis becomes quite tough. In this case of ambiguity, we use fuzzy logic to calculate the antenna's performance index. A variety of antenna parameters will be fed into the fuzzy inference system, which will make a judgment based on a set of rules. The crisp numbers are turned into fuzzy values using the fuzzification process, then evaluated and defuzzied to obtain the antenna's performance index. The fuzzy inference system will be developed in MATLAB, and the overall system will be modeled in Simulink.

A radiated element is a type of electrical equipment that converts electric power into radio waves, allowing the signal to be transmitted over open space
Maintaining parameters values, we propose, for the various antenna structures, abased fuzzy logic functions solution to be used for performance analysis
The antennas [20] are simulated for frequency ranges ranging from 1MHz to 10MHz, and the performance characteristics are assessed with a fuzzy inference algorithm to provide a performance index
Summary
A radiated element is a type of electrical equipment that converts electric power into radio waves, allowing the signal to be transmitted over open space. It converts incoming radio signals to electrical impulses. The frequency of operation [1], as well as the application, are two of these criteria. The antenna's performance is determined by numerous criteria such as return loss, reflection coefficient, and voltage standing wave ratio. Multiple antenna topologies are modeled for performance characteristics for different frequencies using MATLAB's antenna [2] toolbox. These parameters are fed into the fuzzy inference system, which analyzes the antenna's performance while taking all of the parameters into account. The fuzzy inference system is created using a rule set drawn from antenna experts'
