Description

Miniaturized on-vehicle parabolic antenna Technical Field The utility model relates to a parabolic antenna, in particular to a miniaturized vehicle-mounted parabolic antenna. Background A parabolic antenna refers to a planar antenna consisting of a parabolic reflector and an illuminator (feed) located at its focal point. A metallic paraboloid of revolution, a cut paraboloid of revolution or a cylindrical paraboloid of revolution is generally used as a reflector, and a horn or a dipole with a reflector is used as a feed source. The small-sized parabolic antenna is a satellite communication antenna commonly used on an emergency communication vehicle, most of the small-sized parabolic antennas are installed at the top of the communication vehicle by adopting an adjustable bracket so as to adjust the direction of the antenna when the vehicle stops, however, the adjustable bracket can adjust the direction of the antenna in a large range, but the parabolic antenna is large in size and can protrude from a high distance of a vehicle roof, so that the trafficability of the vehicle is severely restricted, and the antenna is easily damaged due to collision of foreign objects in the running process of the vehicle, and the antenna is to be improved. Disclosure of utility model The utility model aims to provide a miniaturized vehicle-mounted parabolic antenna, which solves the problems in the background technology.
