Embodiment Construction

[0032] 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.

[0033] 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 specifically discloses a Beidou GPS dual-mode vehicle-mounted intelligent control system composed of circularly polarized antennas of different frequency bands, wherein the frequencies are tower cascaded from low frequency to high frequency from bottom up, the uppermost layer is an S patch antenna, the second layer is a B1L combined patch antenna and the third layer is a B3 patch antenna; the uppermost layer selects a single-feed point center coaxial feed chamber to realize the circularly polarized antennas, the middle layer selects a four-feed point coaxial feed to realize positive and negative phase differences through a power distribution network, and the third layer selects a four-feed point feed to realize the right-hand circular polarization at o degree, 90 degrees, 180 degrees and 270 degrees, which can not only meet the requirement of high-precision positioning function of RNSS, but also realize the requirement of transmission and reception function of RDSS. This antenna adopts the micro-band antenna multi-feed point technology to improve the phase center stability of the antenna such that the phase center error is greater than or less than 2mm and the microstrip patch antenna tower overlay technology is compatible with both RNSS navigation frequencies (BD2-B3, BD2-B1, GPS-L1) and RDSS transceiver frequencies (BD-L, 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...
