Background
Microwave communication is a communication system using microwaves as carriers, and an antenna in the microwave system is used for completing conversion from guided waves to radiated waves. Specifically, radio frequency signals are converted into electromagnetic waves on a transmitting link and radiated to the space, and the electromagnetic waves are converted into radio frequency signals on a receiving link.
The structure of the antenna in microwave communication usually takes the form of a parabolic antenna, and the common parabolic antennas are classified into a feed-forward antenna and a feed-backward antenna. The primary lobe pattern of the feed-forward antenna is determined by the feed. The feed source is arranged on the focus of the parabolic reflecting surface. The primary lobe pattern of the feedback antenna is determined by a composite feed source system formed by the feed source and the secondary reflecting surface together. The feed source is arranged in the center of the parabolic reflecting surface, and the virtual focus of the auxiliary reflecting surface is coincided with the real focus of the parabolic reflecting surface. In essence, in a feed-back antenna, the feed is a primary antenna that radiates electromagnetic waves towards the subreflector. The parabolic reflector is a passive device, and reflects energy radiated from the feed source reflected by the sub-reflector, and the reflected beam has a certain directivity and has the same phase on a plane perpendicular to the propagation direction. The sub-reflecting surface is generally formed by spraying metal powder on the surface of a medium. The feedback antenna structure is a dual-reflector antenna, in which the parabolic reflector is a main reflector and the sub-reflector 4 is a sub-reflector. The rear feed antenna may also be referred to as a dual reflector antenna.
In the field of dual-reflector antennas, the conventional mounting method is to position the sub-reflector, then trim the sub-reflector and the mounting surface of the supporting rod, and assemble and process the mounting holes of the sub-reflector and the supporting rod.
The traditional installation method has very high requirements on the technical level of an assembler and is time-consuming and labor-consuming. For modern models of mass production, the conventional mounting methods are no longer suitable.
