Embodiment

[0053] In this embodiment, the metal circular table 21 at the center of the metal support base 2 is a cylinder. The lower part of the cylinder is 10 mm in height and 24 mm in diameter; the upper part is 11 mm in height and 22 mm in diameter. Four S feeder through holes 28 with a diameter of 3.2 mm are evenly distributed on a circle with a distance of 8 mm from the center. The bottom groove 22 of the metal support base 2 has a depth of 10 mm and a diameter of 120 mm.

[0054] The diameter of the through hole 34 at the center of the probe printed board 3 is 22mm, and there are four in-line probes 32 with a width of 3mm and a length of 38.5mm starting from 18.5mm from the center. The needles 32 are evenly distributed around the circumference.

[0055] In the L / S integrated microstrip printed board 4 , the S-band microstrip patch 41 and the L-band microstrip patch 42 are obtained by etching the dielectric base plate 43 . The base material of the dielectric base plate 43 is F4BM...

Abstract

The present invention discloses a portable economical-type high-precision navigation antenna for all navigation systems. The antenna comprises an antenna cover, a metal support base, a probe printed board, an L / S integrated micro-strip printed board, L feeder lines, S feeder lines and a bridge printed board. According to the portable economical-type high-precision navigation antenna for all navigation systems, an L frequency-range antenna and an S frequency-range antenna are separately corroded on the two sides of a layer of printed board, the L frequency-range antenna is fed by using micro-strip probes under the printed board, and the S frequency-range antenna is fed by using the four S feeder lines penetrating in a metal round platform. The antenna has the advantages of compact structure and small size. The antenna can cover all frequencies of all existing navigation systems and has high phase center stability and high anti-multipath capability; moreover, the antenna is easy to process and assemble, free of adjusting, small in size and low in cost.

Description

technical field [0001] The invention relates to the technical field of satellite navigation antennas, in particular to a portable economical high-precision navigation antenna for a full navigation system. Signal. Background technique [0002] With the continuous development of my country's "Beidou No. 2" satellite navigation and positioning system, various applications based on the Beidou system have spread to various fields such as economic construction and scientific research, and with the continuous improvement of the Beidou system, various applications are also increase, and develop in the direction of multi-system and multi-mode. As the front-end hardware equipment of the entire receiving system, the performance of the satellite navigation antenna is directly related to the accuracy and sensitivity of the entire system. Portability and cost control are more important factors for the large-scale promotion of the entire system. [0003] At present, high-precision naviga...
