specific Embodiment

[0029] Specific examples: see Figure 1-Figure 11 As shown, the embodiment provided by the present invention: an ultra-wideband high-precision satellite navigation antenna, comprising a concave metal radiating sheet 1, a feeding coupling sheet 2 and a feeding PIN pin 3; the feeding coupling sheet 2 has four branches and is separated in sequence The 90 degrees are evenly distributed in four directions, the middle is supported by screws 4, and the ends of the branches are supported by metal PIN pins 3 and connected to the feed. The height of the PIN pin 3 is shorter than the middle support screw, so that the four branches form an inclined coupling feed.

[0030] In a preferred embodiment of the present invention, the concave metal radiating sheet 1 is inverted on the top of the antenna in the shape of a dish, and there are four plastic screws 5 around it for supporting and fixing.

[0031] In a preferred embodiment of the present invention, the peripheral metal ground 6 is elect...

Abstract

The invention discloses an ultra-broadband high-precision satellite navigation antenna, which comprises a radiation piece, a feeding coupling piece and a feeding PIN needle; the feeding coupling piece is evenly distributed around the radiation piece, and the feeding PIN needle and the feeding The electric coupling sheet is connected, and the present invention reduces the weight of the high-precision satellite navigation antenna, which is beneficial to the reduction of the shrinkage of the terminal equipment, especially for land resource surveying and mapping measurement and aviation navigation; and the electroplating process or copper foil attached And the processing method is mature, and the production cost is low, which is conducive to the large-scale application of the product. With good economic benefits.

Description

technical field [0001] The invention relates to an ultra-wideband high-precision satellite navigation antenna. The antenna has light weight, low cost and stable phase center, and can be used in high-precision positioning related fields such as surveying and mapping, car navigation, and unmanned autonomous driving. Background technique [0002] With the continuous improvement of the construction of my country's Beidou satellite navigation system, applications related to Beidou positioning and navigation have been vigorously developed, covering traditional surveying and mapping to current hot spots such as unmanned autonomous driving and drones. In order to achieve high-precision navigation and positioning, the current positioning equipment often receives satellite signals of different frequency bands of Beidou, GPS (Global Positioning System), and GLONASS (Global Navigation Satellite System) navigation systems at the same time to achieve multi-system joint positioning, and fu...
