Vsat antenna
Antenna attaches much importance in the earth station, the antennas are divided
into different catogories, this article mainly introduces Cassegrain Vsat antenna and the
working priciple of Vsat
antenna.Vsat
antenna is an importanct part in the Satellite communication earth stations.
The Vsat antenna mainly do the energy transformations between electric energy of
alternating electrocircuit and electromagnetic wave in the space. According to
the required operational frequency, polarization and direction transmit and
receive signals, and equivalently amplify the transmiting power and receiving
power.
Accoring to the antenna geometry, in the earth station there are
axialsymmetry and nonaxialsymmetry antenna structures.At present in the actual
application there are truss antenna structure, kingpost antenna, turnable
antenna mount...etc. According to the function and application it can classified
as full motion antenna, limit motion antenna, vehicle mounted antenna,Marine
antenna, portable antenna...etc. Blow take the Cassegrain antenna as example,
introducing the working principle and technical specification for the Vsat antenna.
