Cobham Antenna Systems Introduces 6-Way Mini Multi Sector Antenna for COFDM
9, 2010 - Cobham Antenna Systems, Microwave Antennas has designed a miniature Multi Sector antenna in the
2.0-2.7GHz band for use with COFDM radios.
COFDM provides significant benefits over conventional analogue microwave transmissions, especially in high
multi-path environments such as dense urban areas. It is possible to virtually eliminate fade even in non
line-of-sight (NLOS) situations through the use of spatial antenna diversity schemes. For this reason, COFDM
systems are being used for National Security, Police and Military applications where it is vital that integrity of
video and data links is maintained under the most imposing situations.
The new model, MSA6-2.4V/1795, has 6 antennas and is unusually small for this type of antenna. It is contained
within a rugged housing measuring just 300mm x 155mm diameter (12 inches by 6.5 inches).
Five of the
antennas are sectors, each with up to 9dBi peak gain and azimuth beamwidth of 120 degrees. They provide a high
level of overlap so that the COFDM radio can use 3 to 4 sectors’ worth of data at any time for recombination to
ensure that localized transient fading is eliminated, which is especially associated with mobile applications.
The sixth antenna is up-looking to provide complete hemispherical coverage. This increases the practical
applications and maximizes operational flexibility for the antenna for rapid deployment as well as temporary and
