Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] The application principle of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] The double-coupled short-circuit loading GNSS navigation antenna of the embodiment of the present invention is divided into five layers, and the lower four layers of printing plates are pressed together to form a feed network with a wire structure. The short-circuit probe and the vertical part of the feed L probe use a 1mm diameter copper needle, the upper layer uses a f4b dielectric board with a thickness of 1mm.

Abstract

The invention discloses a double-coupling short-circuit loading GNSS (global navigation satellite system) navigation antenna. The double-coupling short-circuit loading GNSS navigation antenna consists of an upper layer and a lower layer, wherein the lower layer is a four-feed network layer, and the upper layer is a surface mounting layer; the surface mounting layer stretches out a metal strap layer towards four apexes of the double-coupling short-circuit loading GNSS navigation antenna, the metal strap layer is coupled with a first short-circuit metal strap and is short-circuited to the next floor layer, a second short-circuit metal strap layer is coupled with the first short-circuit metal strap at the same time and is short-circuited to the floor, so that a double-short-circuit loading structure is formed. The double-coupling short-circuit loading GNSS navigation antenna adopts two layers of L probe feeds, and air mediums are arranged between the two layers of the L probe feeds. Through the change of the structure of the double-coupling short-circuit loading GNSS navigation antenna disclosed by the invention, the application of double frequency bands can be realized, and a GNSS antenna which is smaller than the antenna in the prior art is invented by using the new technique.

Description

technical field [0001] The invention belongs to the technical field of satellite navigation antennas, in particular to a double-coupled short-circuit loaded GNSS navigation antenna. Background technique [0002] With the rapid development of satellite navigation technology, many countries have established their own satellite navigation systems, such as GPS in the United States and GLONASS in Russia, which have been widely used. Europe's Galileo and China's Beidou Compass have also launched services. In order to solve the problem of single system coverage blind spots, the future satellite navigation system will adopt a mode compatible with multiple satellite navigation systems. A system using this mode is called a Global Navigation Satellite System (GNSS). Antenna is an essential part of satellite navigation system, and it directly plays a decisive role in the performance of the navigation system. Therefore, broadband multimode navigation antenna (GNSS antenna) has become a...
