Abstract

The invention discloses a five-frequency-section user machine antenna being compatible with Beidou and GPS (Global Positioning System) functions to be used for solving the problem that isolation between the multi-frequency-section antenna layers is poor. The five-frequency-section user machine antenna being compatible with the Beidou and GPS functions comprises a Beidou first S-frequency-section patch antenna (2), a L-frequency-section patch antenna (3), a Beidou second B1-frequency-section patch antenna (4), a B3-frequency-section patch antenna (5), a feed network plate (6), a base plate (7) and a feed probe (8); an isolating ring is arranged close to a center of the Beidou second B1-frequency-section patch antenna (4) and the B3-frequency-section patch antenna (5); an input end of the feed network of the L-frequency-section patch antenna (3) is provided with a U-shaped nodule; the four patch antennas (2), (3) and (4) and (5) are sequentially arranged from high to low and top to bottom; the feed network plate (6) is fixed at the lower end of the structure; the upper end and the lower end of the feed probe (8) are respectively connected with a corresponding patch and the feed network. The five-frequency-section user machine antenna is compatible with the Beidou and GPS functions and is applicable to vehicle-mounted and shipborne navigation equipment.

Description

technical field [0001] The invention belongs to the technical field of antennas, and specifically relates to a five-band dual-circular polarization transceiver antenna compatible with Beidou No. 1 S frequency band, L frequency band, Beidou No. 2 B1 frequency band, B3 frequency band, and GPSL1 frequency band. Used in vehicle, ship and other navigation equipment. Background technique [0002] The satellite navigation system can continuously provide high-precision three-dimensional position, speed and precise time information for various civil and other carriers on land, sea, air and space around the world. At present, foreign satellite navigation systems mainly include GPS in the United States, GLONASS in Russia, and Galileo in Europe. Since 2003, my country has successively developed Beidou-1 and Beidou-2 satellite navigation systems with independent intellectual property rights, which can provide accurate positioning comparable to GPS and timing with an accuracy of 20 nanos...
