Description

But dull and stereotyped portable satellite communication terminal of KA-KU dual-frenquency switching Technical Field The invention relates to the technical field of satellite communication, in particular to a portable flat-plate satellite communication terminal capable of KA-KU double-frequency switching. Background In recent years, high-throughput satellites have evolved rapidly. For example, two recent high-flux satellites in China often adopt ku or ka frequency bands, wherein a middle satellite No. 16 satellite emits in 2017 on the 4 th month and 12 th day, a small station adopts ka frequency bands, points to 110.5 degrees of synchronous satellite orbits in east longitude, 26 user beams are provided, and the satellite beams cover China and offshore areas, so that the satellite can be applied to the fields of distance education, medical treatment, internet access, airborne and ship communication, emergency communication and the like. The satellite station transmits successfully in 7 months and 9 days in 2020, the satellite station transmits in Ku frequency band, the total communication capacity reaches 50Gbps, the single beam capacity can reach 1Gbps, high quality voice and data communication service can be provided for users, and 90 user beams are adopted to realize global coverage in visual range. Because the high-flux satellite adopts a spot beam mechanism, different frequencies can be adopted in different areas, and very high EIRP is given in a single area, the signal strength which can be received by a satellite small station is greatly improved compared with that of the traditional satellite. For the traditional satellite, the lowest caliber is 0.8m, and under the high-flux satellite, the caliber of the lowest antenna surface can reach 0.3m, so that the equipment is miniaturized, and the volume, weight and thickness of the equipment can be greatly reduced. However, the conventional transmission mode cannot meet the requirement of equipment miniaturization. Thus, there is an urgent need to develop smaller, precise actuators. The general Ku/Ka switchable equipment adopts a feedforward antenna, but the equipment is large in size and inconvenient to carry, the equipment is assembled by side lobes, more parts such as a feed source rod, a power amplifier, a low-noise amplifier and the like are required to be replaced during replacement, the use is complex, the flat-panel equipment is widely used due to the advantages of small size, convenience in use, attractive appearance, convenience in storage and the like, but the equipment used in the market is generally single-frequency, and the KU/KA double-frequency can not be replaced. Disclosure of Invention The invention aims to provide a flat portable satellite communication terminal capable of KA-KU double-frequency switching, which aims to solve the problems that in the background art, a Ku/Ka switchable device adopts a feedforward antenna, but the device is large in size and is not beneficial to carrying. In order to achieve the purpose, the technical scheme is that the flat portable satellite communication terminal capable of being switched between KA and KU comprises a KA/KU antenna feeder, wherein an electric control main case is fixedly arranged on the lower side of the KA/KU antenna feeder, a supporting base is fixedly arranged on the lower side of the electric control main case, a quick-release screw is fixedly arranged at the upper end of the electric control main case, an antenna feeder shell is fixedly arranged at the lower end of the electric control main case, a pitching knob is fixedly arranged at one end of the antenna feeder shell, a battery is fixedly arranged on the lower side of the antenna feeder shell, and an azimuth hollow motor and a speed reducer are fixedly arranged at one end of the battery.
