product description:

The 1.8-meter satellite communication antenna adopts a single bias structure, and the antenna structure strives to be simple and practical. The antenna curve is relatively flat, and at the same time, it adopts a split structure of the reflective surface, and the number of splits is 2 panels, which makes it convenient for transportation and storage. The antenna fixing methods are flexible and diverse. According to the installation location conditions, it can be fixed by the foundation or by a movable foundation.

The working principle of a single-bias parabolic antenna, the basic electrical characteristics of a parabolic antenna is to place the feed source at the focus of the parabola (feedforward) or place the virtual focus of the secondary surface at the focus of the parabola (dual-mirror rear feed, the feed source is placed on the secondary surface Another virtual focus of the signal), when the signal electromagnetic wave is transmitted, the spherical wave emitted by the feed source is reflected into a plane wave, and reaches equal phase on the antenna reflection surface aperture plane; when receiving the signal, according to the reciprocity principle of antenna transmission and reception, the signal electromagnetic wave follows the opposite path transmission. The characteristic of the single-offset antenna is that by intercepting a part of the circular symmetric paraboloid, the feed source is deflected by a small angle relative to the focal axis of the paraboloid to achieve illumination. While the antenna has the characteristics of a parabola, the level of the first side lobe of the antenna is improved.
