Abstract

The embodiment of the invention relates to the technical field of antennas, and discloses an integrated GNSS antenna device with a multipath suppression function. The integrated GNSS antenna device comprises a first satellite positioning antenna, a second satellite positioning antenna and a communication antenna, wherein the first satellite positioning antenna comprises a first dielectric layer, afirst metal patch and a first short-circuit choke branch knot, the first short-circuit choke branch knot is arranged on the first dielectric layer and located on the periphery of the first metal patch, the second satellite positioning antenna comprises a second dielectric layer, a second metal patch and a second short-circuit choke branch knot, the second dielectric layer is arranged on the firstmetal patch, the second metal patch is attached to the face, away from the first metal patch, of the second dielectric layer, the second short-circuit choke branch knot is located on the periphery ofthe second metal patch, and the communication antenna is arranged on the first dielectric layer. According to the invention, the integrated GNSS antenna device can improve the multipath inhibition capability of the GNSS antenna so as to improve the positioning precision of the antenna device.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to an integrated GNSS antenna device with a multipath suppression function. Background technique [0002] In recent years, with the development of GNSS (Global Navigation Satellite System, GNSS) broadband full-frequency global navigation satellite antenna technology, the same antenna device has achieved full-band coverage and reception of a variety of different satellite signals, which has greatly improved The performance of the antenna device to receive satellite signals. However, it is found in practice that the antenna device in the related art has serious multipath effects, which affects the signal reception of the satellite positioning antenna in the antenna device, which is not conducive to improving the positioning accuracy of the antenna device. Contents of the invention [0003] The embodiment of the present application discloses an integrated GNSS antenna dev...
