DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Figure 1 shows an embodiment of portable Ku.c.s waveband satellite ground receiving and emitting device according to this invention. The device consists of a cabinet (2) and an inflated body (3) connected to and fixed inside the cabinet (2). The receiving and emitting device, and control unit are mounted inside Cabinet 2. Solar energy panel can be fixed on the back of the cabinet cover (1) and feed a supply battery, not represented. The cabinets contain a foldable dish antenna. The control unit has a push-in and ejection design. The improvement of this invention lays on the parabolic antenna for reception and emission. The dish has an inflatable structure with an inflatable gasbag. The upper end of antenna is fixed inside the top cover of cabinet 1 and the lower end is fixed inside the cover of cabinet 2. When released, the

cabinets

1 and 2 open by actuation of an active spring or piston, engaging cabinet supports keep the cabinets open. Once inflated, body 3 expands. A mini-inflating pump will feed air into the body via a connected air circuit pipeline. When the body is filled with air, it changes its shape into a paraboloid structure. Preferably the body has a double layer beehive structure. According to a preferred embodiment of the invention the external surface of the inflated body paraboliod is coated with a silver layer, which forms on the surface a conductive reflector. A antenna feed assembly 6 with telescopic feed assembly support is located on in the center of the inflated body's surface. The above-mentioned telescopic feed assembly support 5 is fixed to the base 4, located in the center of inflatable body 3, through a pivot 7. The antenna feed assembly support 6 will focus through the telescopic rods, switching over the searched Ku.c.s wave bands. The telescopic displacement can be either driven by hydraulic displacement device consisting of control unit, hydraulic circuit and hydraulic pump, or by an electric motor driven multisection screw telescopic support. The telescopic antenna feed, either hydraulic or screw-motor driven assembly, rising and falling structure is the traditional antenna type rise and fall device.

The hydraulic pump or motor mentioned above may be controlled automatically through a microprocessor. Besides, it is also possible to effect a manually controlled regulation, i.e. the waveband is accurately focused with the help of multisection pull rods with regulation wave signs engraved on the rods.

This type of portable Ku.c.s waveband satellite ground receiving and emitting device can be automatically controlled through a microprocessor. After switching on, all the actions, including the inflation of antenna with air pump, pressurization of hydraulic system for the power source support of feeder, all-round expansion of gasbag antenna and selection of wavebands, can be completed under the instruction of the micro-processor program. As soon as the system finishes all tasks, it can fold fully and automatically once the operator presses "OFF" on the remote controller.
