Description

technical field

[0001] The invention relates to the technical field of antennas, in particular to a broadband single-dielectric-layer GNSS measuring antenna device. Background technique

[0002] With the rapid development of GNSS (Global Navigation Satellite System), especially the rise of my country's Beidou satellite navigation industry, the demand for multi-system navigation capabilities has also increased. In order to meet the application requirements of terminal equipment compatible with the four major navigation systems (Global Positioning System, Glonass Positioning System, Galileo System and Beidou Satellite Navigation System), the antenna should have a wide gain bandwidth and beam bandwidth, and the system is required to be compatible Stronger and more compact structure.

[0003] In view of the current design requirements of high-precision multi-system GNSS measurement antennas, in terms of satellite signal reception performance, it is necessary not only to ensure ...
