What is SMART ANTENNA?
  • A smart antenna consists of an antenna array,
    that changes the array pattern in response to the
    signal environment to improve the performance .

3
TYPES OF SMART ANTENNA
  • Smart antenna systems are classified into two
    types,
  • SWITCHED BEAM ANTENNA
  • ADAPTIVE ARRAY ANTENNA

4
SWITCHED BEAM ANTENNAS
  • A finite number of fixed, predefined patterns or
    combining strategies(sectors).
  • These antenna systems detect signal strength,
    choose from one of the several predetermined,
    fixed beams, and switch from one beam to another
    as the mobile moves throughout the sector.

5
SWITCHED BEAM ANTENNAS
6
ADAPTIVE ARRAY ANTENNA
  • These are infinite number of patterns.
  • Adaptive antenna technology provides optimal gain
    while simultaneously identifying, tracking and
    minimizing interfering signals.

7
Benefits of SWITCHED BEAM and ADAPTIVE ARRAY
Systems
  • Integration.
  • Range or Coverage.
  • Interference suppression.
