Multibeam antenna arrays

Abstract

This chapter begins with a brief introduction of basic concepts in antenna arrays which is followed by slightly advanced concepts including smart antennas and related systems. This helps the readers to acquire basic knowledge necessary to understand the concepts of multi-beam antennas and various beam-forming networks outlined in the sessions that follow. The world of engineered materials which become an important research area is also outlined to broaden the knowledge of the readers. This chapter concludes with some recent multiple-beam antenna design examples with metamaterial technology.
