And a receiving antenna of a low orbit satellite with high quality, high reliability, high portability, and competitive price is one of key elements determining commercialization and mass popularization.
The dish antenna of the conventional satellite has a number of disadvantages, such as the volume that the conventional passive receiving dish antenna is a metal curved surface with a diameter of generally over 60cm to 120cm and a feed end length of the antenna of over 30cm, and an additional metal bracket is required to support the fixed elevation angle and the weight of the antenna, so that the volume of the antenna can exceed 60cm x30cm. The weight of the antenna metal framework based on the volume can reach more than ten kilograms or tens of kilograms. If mechanical elevation and free angle scanning are added, the volume and weight will increase. Appearance-based on volume or weight factors, conventional satellite reception is limited in use arrangement. Opaque metallic bodies are visibly apparent. Therefore, the large, heavy, and mechanical beam scanning technology requiring elevation and free angle rotation, coupled with the high price and other factors, directly limit the market development for in-vehicle, small aircraft and other mobile satellite communications, and a large number of portable satellite communications.
