Specialist engineers and researchers examine microwave antennas and more specifically planar versions, which are the types of antenna preferred at microwave frequencies in modern integrated communication systems. They explain the principles of planar and/or small volume antennas, problems of design and manufacture, and constraints and limitations presented by the antenna within the body of the communication system. Among specific topics are the transmission line model, electrical equivalent circuit of a printed antenna, circularly polarized antennas, and reconfigurable antennas.

Compact Antennas for Wireless Communications and Terminals deals with compact microwave antennas and, more specifically, with the planar version of these antennas. Planar antennas are the most appropriate type of antenna in modern communication systems and more generally in all applications requiring miniaturization, integration and conformation such as in mobile phone handsets.
The book is suitable for students, engineers and scientists eager to understand the principles of planar and small antennas, their design and fabrication issues, and modern aspects such as UWB antennas, reconfigurable antennas and diversity issues.
