Description

Square antenna fixture Technical Field The utility model relates to the technical field of antenna assembly, in particular to a square antenna clamping mechanism. Background Square antennas are a common type of antenna commonly used in the fields of wireless communications, radar, satellite communications, and the like. The antenna has the advantages of simple structure, easy design and manufacture, and good radiation characteristics under certain frequency bands. The square antenna can be in the form of a microstrip antenna, a patch antenna or an array antenna and the like, and is widely applied to mobile communication, wi-Fi, bluetooth and other devices. The square antenna needs to be kept stable during operation, and position deviation caused by vibration or external force is avoided, so that signal transmission quality is affected. Disclosure of utility model The utility model aims to provide a square antenna clamping mechanism which can fix square antennas with different sizes and ensure signal transmission quality. In order to solve the technical problems, the utility model adopts the following scheme: The utility model provides a square antenna fixture, includes the base, is equipped with the guide rail on the base, along sliding connection have two at least sliding plates on the guide rail length direction, be equipped with the fixture that is used for centre gripping square antenna upper and lower both ends on the sliding plate, be equipped with the hold-down mechanism that is used for avoiding square antenna back-and-forth movement on the fixture.
