In day-to-day activities, portable wireless and mobile communication devices and technologies are becoming an integral part of human life. These systems need compact, high gain, high directivity and large bandwidth antennas to communicate voice, video, data, and multimedia information at high data rates. The limitations of microstrip patch antennas restrict to fulfill these challenges. This book presents different configurations of planar metamaterial antennas to overcome these limitations. In this book, metamaterial loaded ESAs, MI waveguide loaded microstrip patch antennas have been...
