ANTENNA SYSTEM MOUNTING MOBILE VEHICLES

摘要

An antenna system is provided to reduce power consumption by reducing capacity of an azimuth chase motor for controlling an azimuth of a rotary part. An antenna system(10) includes a rotary part(200), an outer fixing part(500), and an inner fixing part(300). The rotary part is positioned inside a radome(100). The rotary part transmits and receives signals for satellite communications. The outer fixing part is positioned outside the radome. The outer fixing part includes a frequency conversion part(520), a power distribution part(530), and a data collector(540). The frequency conversion part converts a frequency of the signals for satellite communications. The power distribution part distributes a power source to elements. The data collector delivers a control signal among a main system(20), the rotary part, and the outer fixing part. The inner fixing part is positioned inside the radome. The inner fixing part includes an azimuth chase motor(310) for controlling an azimuth of the rotary part.
