In parallel with the wireless communication growth, the need for higher quality transmission and wider coverage rises. As a result of that, a better use of the electromagnetic radiation wavelength is developed; in order to achieve that a better and deeper understanding of the antenna's specifications and properties is highly needed. This book is introduced to provide and help the readers to achieve a better understanding of the antennas field. The problems and solutions introduced are covering most of the very difficult parts of the field. It provides the solutions of different types of antennas such as dual feeding and triple feeding for full wave dipole antenna, monopole, radars, cellular systems, and many more. The aim of this book is to increase the readers understanding and capabilities in solving and analyzing such issues and have the ability to overcome them if they arise in any form in the future.
