The prior art mostly uses a GNSS antenna as a core antenna, which is placed in the center of the device, while the communication antenna is around the GNSS antenna. When the system is more and more complex and the number of the antennas is more and more, the traditional design thinking is to combine the separate designs of each antenna, if the installation design is unreasonable, the performance and the reliability of each antenna are easily affected, if the situation occurs: the communication antenna may interfere with GNSS signals, and the station transmitting signal may interfere with the reception of the WiFi antenna. The high-precision GNSS antenna is used as a core of positioning and is operated with optimal performance, and is undoubtedly placed in the center of the device, so that stable phase center and high-precision positioning performance are ensured. Communication antennas (such as radio station antennas) are arranged on the periphery of the GNSS antenna, the influence is too large when the communication antennas are too close to each other, the whole equipment is too large when the communication antennas are too large in distance, and the cost is increased; more importantly, the radio station antenna has low frequency, the required radiation area is larger, and the high-precision performance of the GNSS antenna is greatly affected; in addition, the omnidirectional performance of the radio antenna is changed into orientation after being influenced by the GNSS antenna and the reflecting plate, and the dead zone is increased. The existing antenna has the problems of installation compatibility, interference and the like of different antennas, and the use is affected.
Accordingly, the prior art has drawbacks and needs improvement.
