| Abstract: |
| International developments in Smart Antenna(SA) are introduced,with emphasis on the study in Japan and Europe.Then the merits as well as demerits of analog SA and digital SA,single RF channel SA and multiple RF channel SA,and regular SA and MIMO are discussed respectively,each accompanied by some corresponding newly emerged technologies.Finally advantages of SA application in mobile communication are presented,and the ESPAR developed by ATR is introduced. |
