CHAPTER 6

SMART ANTENNAS

Jack H. Winters

INTRODUCTION

Throughout the world, including the United States, there is significant research and development on smart antennas for wireless systems. This is because smart antennas have tremendous potential to enhance the performance of future generation wireless systems as evidenced by the antennas' recent deployment in many systems.

This chapter covers smart antenna technology, including software and system aspects. First the two basic types of smart antennas, adaptive and phased arrays, are described and then their current use and proposed use in future wireless systems is discussed. Then the key research issues that came up at the U.S. workshop and at the various sites the WTEC panel visited are presented. Finally, conclusions are presented along with the technology assessment of the U.S., European, and Japanese companies.
