Problems solved by technology

The traditional design adopts the idea of ​​separating each antenna, which increases the number of antennas, increases the cost of equipment, and is not conducive to miniaturization design
[0003] At present, the antennas designed separately are generally integrated together, such as directly placing the 4G antenna and the WIFI antenna around the GNSS antenna. Although the size of the antenna is reduced to a certain extent, this method does not take into account the interference between the antennas. and coupling, it is particularly easy to interfere with GNSS signals, reduce positioning accuracy, and even cause satellites to lose lock

Abstract

The invention discloses a multifunctional GNSS antenna, and belongs to the technical field of communication. The multifunctional GNSS antenna comprises a PCB, a first dielectric plate and a first radiation part which are arranged in sequence, and the PCB is connected with the first radiation part through a first feed part. And the first dielectric plate is also provided with a second radiation part and a plurality of metallized via holes, the second radiation part is connected with the PCB through a second feed part, the plurality of metallized via holes are arranged around the first radiationpart, and the second radiation part is arranged at the outer sides of the plurality of metallized via holes. According to the multifunctional GNSS antenna, signal interference and coupling of the second radiation part to the first radiation part are effectively reduced, and miniaturization of the antenna is facilitated.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a multifunctional GNSS antenna. Background technique [0002] With the development of Internet of Things communication technology and GNSS satellite navigation and positioning system, GNSS navigation and high-precision positioning equipment are developing in the direction of miniaturization and multi-function. While realizing the navigation and positioning function, it must also have functions such as mobile cellular communication, WIFI, Bluetooth, and private network communication. The traditional design adopts the idea of ​​separating each antenna, which increases the number of antennas, increases the cost of equipment, and is not conducive to miniaturization design. [0003] At present, the antennas designed separately are generally integrated together, such as directly placing the 4G antenna and the WIFI antenna around the GNSS antenna. Although the size of the antenn...
