A person who needs to convey thoughts, ideas, or a doubt can do so through voice communication. Here, communication takes place through sound waves. However, if two people want to communicate who are at long distances, then these sound waves are to be converted into electromagnetic waves. The device which converts required information signal into electromagnetic waves is called “antenna” or “aerial”. It is a transducer which converts electrical signals into electromagnetic signals and vice-versa. Whenever wireless communications occur there arises necessity of an antenna. There are several critical parameters affecting an antenna’s performance that can be adjusted during the design process. They are field patterns, power pattern, resonant frequency, impedance, gain, polarization, directivity, efficiency and beam width. Out of these, parameters like radiation pattern, directivity, VSWR, impedance ,axial ratio, return loss are studied using MATLAB(MATrix LABoratory) antenna toolbox. It provides the library of antennas and arrays, analysis, and visualization tools for using in these applications. It can also integrate with other toolboxes

Axial ratio, Return loss, Radiation pattern
