Abstract

The invention relates to the technical field of radio frequency antennas, in particular to a combined antenna which comprises a first mounting plate, a second mounting plate and a circuit board, the second mounting plate is arranged on the upper surface of the circuit board, the first mounting plate is arranged on the upper surface of the second mounting plate, and the second mounting plate is larger than the first mounting plate, so that mounting positions are formed in the periphery and/or the side face of the upper surface of the second mounting plate. The upper surface of the first mounting plate is provided with a positioning antenna, and the mounting position of the second mounting plate is provided with at least two mobile communication antennas. According to the combined antenna, the positioning antenna is arranged in the center, the mobile communication antennas are arranged surrounding the positioning antenna; mutual influence between the mobile communication antennas and thepositioning antenna can be effectively enhanced; therefore, the stability of the phase center of the positioning antenna is ensured, the positioning antenna can be assisted by using the mobile communication antennas, an accurate positioning signal can be obtained in real time through a carrier phase difference technology, the high-precision measurement requirement in the industry is met, and theoperation efficiency is improved.

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. [0004] A combined antenna, comprising a first mounting board, a seco...
