Description
Technical Field
The utility model relates to an antenna house technical field, concretely relates to an antenna house for cylindrical phased array antenna.
Background
A phased array antenna refers to an antenna that changes a pattern shape by controlling a feeding phase of a radiation element in an array antenna. The control phase can change the direction of the maximum value of the antenna pattern so as to achieve the purpose of beam scanning.
In special cases, the side lobe level, the minimum position, and the shape of the entire directional pattern may be controlled, for example, a cosecant square directional pattern may be obtained, and the directional pattern may be adaptively controlled. When the antenna is rotated by a mechanical method, the inertia is large, the speed is slow, the phased array antenna overcomes the defect, and the scanning speed of the wave beam is high. Its feeding phase is controlled by computer, and its phase change speed is quick (millisecond order), i.e. the maximum directivity of antenna pattern or other parameters can be quickly changed. This is the biggest feature of phased array antennas.
A radome is a structure that protects an antenna system from the external environment. Outdoor antennas are usually placed in the open air to work, and are directly attacked by storm, ice, snow, sand, solar radiation and the like in nature, so that the accuracy of the antennas is reduced, the service life is shortened, and the working reliability is poor.
