Abstract:
Antenna plays a very important role in the communication system. In wireless communication, the antenna is used for transmission and reception of the signal over the distance. There are so many types of antenna, which include wire antennas, traveling wave antennas reflector antenna, microstrip antennas, etc. The application of antennas depends upon the properties of the antenna and also the range of frequency of operation. Thus it is necessary to understand the behavior of the antennas at a various range of operation and choose the best antenna which fits the application. The efficiency of the antenna is determined by its performance parameters. Parameters include VSWR, Return Loss, Directivity, Bandwidth, etc. Thus the analysis of antenna is one of the main areas of concern. In this paper, we simulate various types of antennas and obtain their performance parameter such as return loss, directivity, etc. The antenna will be simulated at different frequencies using MATLAB. The analysis is very difficult when we consider all the parameters. Thus in this point of uncertainty, we employ fuzzy logic to determine the performance index of the antenna. Various antenna parameters will be input to the fuzzy inference system, which will take decision according to the set of rules. The crisp values are converted into fuzzy values by the method of fuzzification and analyzed and defuzzied to get the performance index of the antenna. Fuzzy inference system will be implemented using MATLAB and modeling of the whole system will be done in Simulink.
