Description

Technical Field

[0001] This utility model relates to a parabolic antenna, specifically a miniaturized vehicle-mounted parabolic antenna. Background Technology

[0002] A parabolic antenna is a surface antenna consisting of a parabolic reflector and an illuminator (feed) located at its focal point. Typically, a metallic parabolic rotator, a cut parabolic rotator, or a cylindrical parabolic rotator is used as the reflector, and a horn or a symmetrical dipole with a reflector is used as the feed.

[0003] Small parabolic antennas are commonly used satellite communication antennas on emergency communication vehicles. Currently, most small parabolic antennas are mounted on the roof of the communication vehicle using adjustable brackets to allow for adjustment of the antenna's orientation when the vehicle is stationary. However, while these adjustable brackets allow for a wide range of antenna orientation adjustments, the large size of the parabolic antenna itself causes it to protrude significantly from the roof, severely restricting the vehicle's passability. Furthermore, the antenna is susceptible to damage from collisions with external objects during vehicle operation, which necessitates improvements. Utility Model Content

[0004] The purpose of this invention is to provide a miniaturized vehicle-mounted parabolic antenna to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0011] Compared with the prior art, the beneficial effects of this utility model are:
