Embodiment Construction
[0053] The present invention relates to a portable satellite antenna, such as Figures 10 to 11 As shown, it includes a feed source 1, a feed support rod 5, a reflector 100, a reflector frame 6 for fixing the reflector 100, a base 7, and a reflector elevation adjustment device. One end of the feed support rod 5 is connected to the feed source 1 The other end is detachably connected with the reflector frame 6, so that the feed source can be detached during carrying. The specific connection structure is as Figure 13 As shown, the end of the feed support rod 5 is aligned with the folded edge 60 provided on the reflector frame 6, and a bolt passes through the folded edge 60 and the feed source support rod 5 to fasten them.
[0054] The feed source 1 is fastened and clamped by a U-shaped elastic ferrule 51 , and the elastic ferrule 51 is mounted on one end of the feed source pole 5 so that the feed source 1 is connected to one end of the feed source pole 5 . Such as Figure 12 ...

The invention discloses a portable satellite antenna which comprises a feed source, a feed source fulcrum bar, a reflecting plate, a reflecting plate frame, a base and an elevation adjusting device for the reflecting plate, wherein one end of the feed source fulcrum bar is connected with the feed source, the other end of the feed source fulcrum bar is fixedly connected with the reflecting plate by the reflecting plate frame, and the base is provided with a fixed rod. The elevation adjusting device for the reflecting plate comprises a slider and a connecting rod, wherein the slider is sleeved on the fixed rod and can axially move along the fixed rod, one end of the connecting rod is hinged onto the reflecting plate frame, the other end of the connecting rod is hinged onto the slider, and the slider is provided with a positioning bolt which penetrates through the slider and is abutted to the surface of the fixed rod so as to position the slider. The planar reflecting plate is made of metamaterials and comprises a core layer and a reflecting layer, wherein the reflecting layer is arranged on the surface of one side of the core layer, the core layer comprises at least one slice layer, and each slice layer of the core layer comprises a first sheet base material and a plurality of first artificial microstructures arranged on the first base material. The portable satellite antenna is capable of changing the elevation of the reflecting plate by the aid of the elevation adjusting device for the reflecting plate, so that requirements of different application occasions are met.
Description
technical field [0001] The present invention relates to the communication field, and more specifically, relates to a portable satellite antenna. Background technique [0002] The traditional satellite antenna receiving system is a satellite ground receiving station composed of a parabolic reflector, a feed source, a tuner, and a satellite receiver. The parabolic reflector is responsible for reflecting the satellite signal into the feed and LNB located at the focal point. The feed source is a horn set at the focal point of the parabolic reflector to collect satellite signals, also known as a corrugated horn. There are two main functions: one is to collect the electromagnetic wave signal received by the antenna, transform it into a signal voltage, and supply it to the tuner. The second is to perform polarization conversion on the received electromagnetic waves. The high-frequency head LNB (also known as the down-converter) is to down-frequency and amplify the satellite sign...
