SMART ANTENNAS

Apstrakt
Extensive research activity into the area of smart antenna (SA) cellular applications started at the beginning of the 1990’s. Preference of smart antenna technology is battle for cellular syst em capacity with a limited amount of the radio spectrum. The SA techniques are one of the few techniques that are currently proposed for new cellular radio network designs, which will be able to improve system performance. Introduction smart antennas in to software defined radio will make it possible to optimize radio system design for spatial processing and integrate SA into future adaptive modems.
This information presents a theoretical introduction in to how smart antennas work: definitions, integration of SAs in radio, adaptation algorithms, applications of SAs to multiple access technology, SAs for handsets, MIMO communications systems, SA experiments and consequences of introducing SA.

Key words: antenna, smart antenna, antenna system, radio network.
