Abstract

The invention discloses a bullet train antenna. The bullet train antenna comprises: a first circuit board which is provided with a first board surface; a mobile communication antenna module electrically connected with the first circuit board; a first laminated antenna module electrically connected with the first circuit board, wherein the first laminated antenna module comprises any one or any combination of the following antennas: a Beidou first-generation S-band antenna electrically connected to the first board, a large S communication band antenna electrically connected to the first board,and a Beidou first-generation L-band antenna electrically connected to the first board; and a second laminated antenna module, wherein the second laminated antenna module comprises a first positioningantenna and a second positioning antenna which are laminated in sequence, the second positioning antenna is arranged on the first board surface and is electrically connected with the first circuit board, the first positioning antenna is electrically connected with the first circuit board, and the mobile communication antenna module, the first laminated antenna module and the second laminated antenna module are arranged on the first board at intervals. According to the invention, high-precision positioning and compatible mobile communication of multiple satellite positioning systems can be realized, the size is reduced, and the cost is saved.

Description

Technical field [0001] The present invention relates to the technical field of antennas, and in particular to a train antenna. Background technique [0002] Global satellite navigation system refers to a space-based radio navigation positioning system that can provide users with all-weather three-dimensional coordinates, speed and time information on the surface of the earth or near-Earth space. The principle is that the distance measurement between satellites and users is based on satellites. The difference between the transmission time of the signal and the time it arrives at the receiver is called the pseudorange. In order to calculate the user's three-dimensional position and the receiver clock deviation, the pseudorange measurement requires at least receiving signals from 4 satellites. With the development of global integration, satellite navigation systems are used in various fields such as aviation, car navigation, communications, surveying and mapping, and entertainment. ...
