Information on Base Station Antenna

Antennas play a very important part in a communications system, coupling energy between a transmitter or receiver and the propagation medium. Matching the correct antenna to the set ensures maximum radiated power. In practice, different designs suit different applications, which has led to the design and development of a great many different types of antenna. While an antenna can be as simple as a piece of wire, more suitable antenna designs are available.
     An antenna ideally has the following characteristics (particularly when deployed as part of a mobile communications system):
    

  • Directionality and gain. A compromise must be made between saving transmitter power (having high gain) and requiring high alignment accuracy or directionality (difficult to achieve in the field).

    •     
  • Bandwidth. The antenna should preferably not require readjustment when the frequency is changed (within limits of course).

    •     
  • Low sidelobes. The radiation pattern should have limited power in other than the desired direction to limit eavesdropping, direction finding, jamming and mutual interference.

    •     
  • Size. Antennas should be small and robust for ease of handling.

    •      A base station antenn can be either:
        
  • a sectoring antenna

    •     
  • an omni antenna
