Description

Technical Field

[0001] The utility model relates to the technical field of nested GNSS antenna equipment, in particular to a nested GNSS antenna. Background Art

[0002] GNSS antenna is an important component in positioning equipment. In order to facilitate the installation and fixation of GNSS antenna, it is often necessary to use a nested GNSS antenna device. The utility model patent with patent application number CN202120484567.6 discloses a nested GNSS antenna and a GNSS device. The first step surface is connected to the second step surface through the first inner wall, and the second inner wall is connected to the first surface of the second dielectric structure. The first step surface is the bottom of the mounting groove. The second radiation patch is arranged on the first step surface and extends to the second step surface through the first inner wall. Since the second patch radiation unit is the reference ground of the first radiation patch, the reference gap of the first radiation patch is not reduced through the stepped setting, and since the current is mainly concentrated The first radiating patch is at the edge of the radiation patch, and the edge of the second radiation patch is at the second step surface. Therefore, for the second radiation patch, its reference gap to the ground is increased by one step height. Therefore, this solution can reduce the size of the GNSS antenna under the premise of basically ensuring the gain bandwidth of the antenna. According to its disclosed technical solution, when the existing nested GNSS antenna equipment is in use, on the one hand, the GNSS antenna is often installed on the inner side of the nesting, and thus the position of the GNSS antenna and the signal receiving angle cannot be adjusted as needed. On the other hand, after the nesting is installed and fixed, it is often not conducive to quick disassembly. At the same time, the nesting is prone to loosening or even falling when vibrated, which is not conducive to ensuring the firmness of the nesting.
