Electronic Communication has become a part of man's life. The good knowledge of Electromagnetics and field theory will make us to understand how we communicate electronically. Antenna has a major part in the communication theory. The study of antenna and its radiation pattern is a must for Communication Engineers who work with antennas. Different kinds of antennas are supporting communication field with various uses. An attempt was made in this book to show how a radiation pattern can be controlled with the parameters of the array antenna. Also how Evolutionary ALgorithm can be used in order to get a controlled radiation pattern. Prerequisites Evolotionay Algorithms, Electromanetics and Filed theory, Antennas.
