Full-frequency-band navigation antenna

Abstract

The invention discloses a full-frequency-band navigation antenna which comprises an antenna element, a medium, the floor, a first feed sheet, a second feed sheet, a first feed PIN and a second feed PIN, wherein the medium is placed between the antenna element and the floor, the first feed sheet and the second feed sheet are placed on the medium, and the floor is connected with the first feed sheet and the second feed sheet via the first feed PIN and the second feed PIN respectively. The working frequency band of the antenna element comprises a GPS satellite frequency range, a Beidou satellite frequency range, a Glonass satellite frequency range and a Galileo system satellite frequency range; materials of the medium comprise but not limited to a high-frequency material, ceramics and PCB; the antenna element is, but not limited to, square and circular; and the first feed sheet, the second feed sheet, the first feed PIN and the second feed PIN are made of a metal conductive material. The full-frequency-band navigation antenna has the advantages including that the material cost is low, the frequency band is wide and gains of frequency points are uniform; and only one high-frequency PCB is needed to realize all the above functions.

Description

technical field [0001] The invention relates to an antenna, in particular to a navigation full-band antenna. Background technique [0002] The Beidou satellite navigation system is a global satellite positioning and communication system independently developed by my country. It is also known as the world's four major satellite navigation systems with the US GPS, Russia's GLONASS, and the EU's Galileo system. At present, the United Nations has recognized these four systems together as the core suppliers of the global satellite navigation system, which has changed the long-term lack of high-precision and real-time positioning means in my country, and broken the monopoly position of the United States and Russia in this field. Various types of military and civilian services on land, sea, air and space provide a variety of business guarantees, which are of great significance to improving the modernization of my country's national defense.

AI Technical Summary

Problems solved by technology

Since the Beidou system was oriented to civilian use, there have been a variety of handheld Beidou terminals compatible with multiple frequency bands; Beidou terminals compatible with Beidou first-generation transceivers and Beidou second-generation receiving frequencies include five frequency points such as GPS frequencies. As a result, the size of the antenna is larger, or the size reduction will make the slot spacing of the antenna elements smaller, which increases the difficulty of the production process and hinders the wider application of the multi-frequency Beidou system

[0004] At present, the full-band antennas of Beidou navigation basically use high-frequency material laminated antennas, the gain is not high, and the price and process are relatively complicated.
