Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032] refer to figure 1 , the present invention is formed by superimposing the upper, middle and lower layers of microstrip antennas and power splitter network towers. Divided into the upper layer S patch antenna 1, the second layer B1L patch antenna 2, the third layer B3 patch antenna 3 and the fourth layer power divider network 4. Antenna frequency from high frequency to low frequency, from top to bottom. Therefore, the area of ​​the patch used becomes larger ...

Abstract

The invention relates to a Beidou navigation vehicle-mounted intelligent control system, and particularly discloses a Beidou GPS dual-mode vehicle-mounted intelligent control system. The system is formed by circularly polarized antennas with different frequency bands, wherein the frequencies are stacked in a tower mode from low frequency to high frequency from bottom to top, the upper layer is anS patch antenna, the second layer is a B1L combined patch antenna and the third layer is a B3 patch antenna. The upper layer selects a single-feed-point center coaxial feeder tangent angle to realizethe circularly polarized antenna, the middle layer selects a four-feed-point coaxial feed mode to realize forward and reverse phase difference through a power division network, and the third layer adopts four-feed-point feed to realize right-handed circular polarization of 0 degree, 90 degrees, 180 degrees and 270 degrees. The requirements for a high-precision positioning function of an RNSS can be met, and the requirements for a receiving and transmitting function of an RDSS can be met; the antenna adopts a microstrip antenna multi-feed-point technology to improve the phase center stability of the antenna, so that the phase center error is + / -2 mm, and a microstrip path antenna tower type stacking technology is simultaneously compatible with the RNSS navigation frequencies (BD2-B3, BD2-B1and GPS-L1) and the RDSS receiving and transmitting frequencies (BD-L and BD-S).

Description

technical field [0001] The invention relates to the field of antenna technology, and is applied to Beidou high-precision satellite radio navigation services and satellite radio measurement services, specifically a Beidou multi-band wide-beam circularly polarized antenna, which is suitable for BD2-B3, BD2-B1, GPS- GPS antenna for L1, BD-L, BD-S bands. Background technique [0002] At present, RNSS high-precision positioning antennas are mainly based on high-precision positioning, only for receiving RNSS navigation signals, using BD2-B3, BD2-B1, and GPS-L1 frequency bands, and do not have the ability to send short messages. In the navigation satellite and operation control application system of the satellite navigation system, both RNSS and RDSS services are integrated at the same time. The system can not only provide users with continuous positioning and speed measurement capabilities (so-called passive navigation and positioning), but also perform high-speed data transmissio...
