Abstract

The big diameter parabolic antenna with floor supporting and charging expansion relates to satellite communication antenna to send and receive electromagnetic wave. Wherein, the reflecting object comprises a group of unit charging chamber 1-1 with floor 3 fixed between two chambers; the floor 3 fixes to separation plate 2-1 of holding frame assembly with back end connected to center link frame 4 and top end adhered reflector layer 6; the back end of unit charging chamber fixes to charging device 5; the reflection object has caliber Phi of 5-25m and composes inner layer of aluminum foil material and side layers of plastic thin membrane. This invention decreases weight, volume and cost, and fits to ideal satellite communication antenna.

Description

Technical field: [0001] The invention relates to a satellite communication antenna for emitting and receiving electromagnetic waves, in particular to a large-diameter parabolic antenna supported by ribs and inflatable and expandable. Background technique: [0002] Antenna is an important radio device for transmitting and receiving electromagnetic waves. Without antenna, there would be no radio communication. The communication antennas used on satellites are mostly linear antennas or small-diameter planar antennas due to the limitation of rocket launch volume and effective launch load. It has been proved by experiments that linear antennas or small-diameter planar antennas are not as good as large-diameter parabolic antennas in terms of focusing and collection capabilities, so large-diameter parabolic antennas are especially suitable for long-distance satellite communications. However, existing large-diameter parabolic antennas have hindered the application of large-diameter...
