Problems solved by technology

In the past, parabolic dish antennas were mostly used in mobile communication, and its fatal disadvantages are high profile (that is, high height), large volume, heavy weight, high resistance during driving, and slow speed for star capture, so it is not suitable for high-speed driving. Use under

Abstract

The invention discloses a novel communication-in-motion low-profile planar antenna system comprising an antenna radiation system, a radio-frequency polarization system, a mechanical antenna terminal driving system, a satellite pointing, capturing and tracking system and an indoor unit. The antenna system provided by the invention simultaneously has the abilities of receiving and transmitting horizontal and vertical polarization signals; the dual-band and dual-polarization duplex working mode is realized on two planar antennas; the volume and the weight of the antenna system are greatly reduced while the functions of the antenna system are guaranteed; besides, according to the antenna system, the cost of the low-profile planar antenna system can be reduced effectively, and also the accuracy of the satellite pairing can be guaranteed by combining the radio-frequency polarization system and the mechanical antenna terminal driving system with a motor and electronic scanning; the satellite pointing, capturing and tracking system detects the position of the mobile terminal; and with the accurate control of the mechanical antenna terminal driving system, the accuracy of the satellite pairing and the satellite tracking of the antenna system is greatly improved; and as a result, smooth communication in traveling is kept.

Description

technical field [0001] The invention relates to a satellite mobile communication panel array antenna terminal system in the communication field, in particular to an equipment system suitable for low-profile satellite mobile communication. Background technique [0002] In the field of satellite communications, especially in the case of stationary use, most of them use parabolic dish antennas. This type of antenna is cheap, so it has a large market. However, due to the long distance of the satellite, not only a large gain of the antenna is required, but also a very high star alignment accuracy is required. For applications that are in motion rather than stationary (for example, onboard a vehicle, ship or airborne), the system is much more complex to keep communication going while the vehicle is in motion. [0003] The vehicle-mounted (ship-borne or airborne) satellite mobile communication system is usually also called "communication in motion". In the past, parabolic dish an...
