Antesky design and manufacture C & Ku Band feed system, the user can use only one antenna with receiving 2 bands (C&Ku) simultaneously to get dual frequency band Satellite signal. This kind of antenna has two types, one is prime focus paraboloid front-feed antenna used for Satellite TVRO, another one is Cassegrain antenna used for Satellite reconnoiter receiving 2…
Components 7.3M Dual Band Antenna Reflector There’re 4 toroidal ribs on the reflector; 3 longitudinal ribs; And the thickness of the panel is 2mm Back up structure Adopt the tube with the diameter ofφ50 andφ40; There’re 3 stress nodal points Hub Hub diameter is φ1330×6 Kingpost Kingpost diameter is φ700×8 Bolts used on the kingpost…
Satellites at different earth orbits present various perspectives for many reasons. Usually there are three kinds of orbits in essence, which are high Earth orbit, medium Earth orbit and low Earth orbit. High Earth Orbit It is also called geosynchronous because the satellite seems motionless to the earth at the same turing speed as the earth. These…
Aluminum mesh antenna,When talking about antennas, what will appear in your brain? A paraboloid, a big and high object, white color etc.Actually there are a variety of antennas around us. They divided into variable categories according to different operations, applications, structures, wave length, etc.Today I’d like to know some antennas with you. Look at the following…
1. What is Rain attenuation？ During the operation of the satellite, if it encounters a rainy area, the radio waves emitted by the satellite will not only be partially absorbed by the rain, but the rain will also scatter the radio waves to a certain extent. Under the joint intervention of the two effects, the…
Satellite communication links design aim: 1. Get corresponding communication reliability(BER value, S/N value) when Transmission Power and receiving antenna diameter are as low as possible; 2. Provide design reference for key components of RF system(such as HPA,LNA), and provide design aim for antenna system; 3. Consider the links attenuation under various condition and provide available…
The source of satellite antenna electromagnetic radiation Satellite earth station is used to receive signals from satellite or transmit signals to satellite. Usually satellite earth station consists of antenna, transmitter, receiver, terminal, communication controller and power supply, as shown in Fig.1 below: The satellite antenna, RF transmitter, power amplifier and waveguide transmission feed line among…
