A combination antenna

Abstract

The present invention relates to the technical field of radio frequency antennas, in particular to a combined antenna, which includes a first mounting board, a second mounting board and a circuit board, the second mounting board is arranged on the upper surface of the circuit board, and the first mounting board is arranged on the second mounting board. The upper surface of the board, and the second installation board is larger than the first installation board so that the surroundings and / or sides of the upper surface of the second installation board form installation positions. A positioning antenna is arranged on the upper surface of the first installation board, and at least two mobile communication antennas are arranged on the installation position of the second installation board. In the combined antenna provided by this application, the positioning antenna is set in the center, and the mobile communication antenna is set around the positioning antenna, which can effectively strengthen the mutual influence between the mobile communication antenna and the positioning antenna, thereby ensuring the stability of the phase center of the positioning antenna, and at the same time using mobile The communication antenna can assist the positioning of the antenna, and the precise positioning signal can be obtained in real time through the carrier phase difference technology, which meets the high-precision measurement requirements in the industry and improves the operation efficiency.

Description

technical field [0001] The invention relates to the technical field of radio frequency antennas, in particular to a combined antenna. Background technique [0002] With the continuous development of science and technology, mobile communication technology has also improved, and people are increasingly relying on real-time precise positioning technology, so the traditional GNSS positioning technology can no longer meet the needs of real-time high-precision positioning, so a combined antenna is needed to Instead of static GNSS measurement technology, the combined antenna can obtain accurate positioning signals in real time to meet the measurement needs of engineering stakeout and topographic mapping. Contents of the invention [0003] The present application provides a combined antenna, which aims to replace the existing GNSS positioning antenna to meet the demand for real-time high-precision positioning.
