Problems solved by technology

[0003] The bandwidth advantage of stacked microstrip antennas is not obvious, the antenna beam width is not wide, and the gain at low elevation angles is poor. The width is not wide, the gain is poor at low elevation angles, the structure assembly is also more complicated, and the cost is higher; the beam width of the multi-frequency helical antenna is wider, but the gain is lower
[0004] In the use of GNSS antennas, the problem directly caused by the above-mentioned low elevation angle gain difference is that the anti-multipath effect is relatively poor, that is, the antenna ranging error increases, resulting in insufficient positioning accuracy.

Abstract

The invention relates to an antenna installation seat and an antenna, and the antenna installation seat comprises an antenna substrate, a fixed plate, and an annular reflection plate. The antenna substrate is of a bowl-shaped structure, and the edge of the opening of the bowl-shaped structure is fixed with the fixed plate. The annular reflection plate is located on the fixed late and is fixed withthe fixed plate. The antenna reflection plate and the antenna substrate are located on the same side surface of the fixed plate. The interior of the bowl-shaped structure is provided with a feed support seat. Compared with a conventional product technology, the antenna is simple in assembly, is higher in structural consistency, and is higher in low-elevation gain.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to an antenna mount and an antenna. Background technique [0002] The existing multi-frequency circularly polarized GNSS (Global Navigation Satellite System, global satellite navigation system) antennas are usually in the form of laminated microstrip antennas, metal half-wave array antennas, and helical antennas. Technically speaking, laminated microstrip antennas and Metal half-wave array antennas have achieved a certain frequency bandwidth function, but there are still many problems. [0003] The bandwidth advantage of stacked microstrip antennas is not obvious, the antenna beam width is not wide, and the gain at low elevation angles is poor. The width is not wide, the gain is poor at low elevation angles, the structure assembly is more complicated, and the cost is higher; the beam width of the multi-frequency helical antenna is wider, but the gain is lower. [0004] ...
