Abstract
The utility model discloses a reed GPS (Global Positioning System) antenna, mainly comprising a printed circuit board, wherein the printed circuit board is provided with printed micro-strip lines; a reed is arranged above the printed circuit board and is connected with the printed circuit board by four square pastes; the four square pastes are adjacent to four right-angle edges of the reed; and an antenna corner feed and a hole are arranged in the middle of the reed. According to the antenna of such structure, the upper paste is designed into a metal reed, air is used as a medium, and a micro-strip paste is combined with a separate printed micro-strip, so that the small volume and the good performance can be ensured after a ceramic medium of high dielectric constant is removed. Since the metal reed serves as the upper paste, the printed circuit board serves as the bottom layer of the antenna, and the square pastes carry out the corner feed and are adjacent to orthogonal edges, the circular polarization of feed with a phase difference of 90 DEG is implemented.
Description
Technical field
The utility model relates to a kind of antenna, especially the reed-type gps antenna of global positioning system, Big Dipper navigation positioning system and Internet of things system.
Background technology
Present domestic global position system GPS, the antenna of Big Dipper navigation positioning system adopts the media ceramic antenna more, and its volume is little; Thereby stable performance is widely used; But, contain a small amount of rare earth material, so consume a lot of natural resourcess because its use is ceramic dielectric; Processing technology is complicated simultaneously, and environmental pollution is serious.
The utility model content
The purpose of the utility model is for the deficiency that solves above-mentioned technology a kind of reed-type gps antenna that does not rely on ceramic dielectric to be provided.
In order to achieve the above object; A kind of reed-type gps antenna that the utility model designed, it mainly comprises printed substrate, described printed substrate is provided with printed microstrip line; The top of printed substrate is provided with reed; Be connected through four square patchs between reed and the printed substrate, wherein four right-angle sides with reed are adjacent respectively for four square patchs, and the middle part of reed is provided with antenna angle feedback and perforate.
The resulting reed-type gps antenna of the utility model; Antenna upper strata patch design is become metal spring leaf; Utilize air as medium, adopt microband paste to combine, thereby still can guarantee smaller size smaller and good performance after making the ceramic dielectric of removing high-k with discrete printed microstrip.Make paster by metal spring leaf, printed substrate carries out the angle feedback and passes through square patch adjacent orthogonal limit through square patch simultaneously as the bottom of antenna, and the feed that phase difference is 90 ° obtains circular polarization.The antenna of this structure adopts metal spring leaf and printed substrate to organically combine, and saves resource, and processing technology is simple, debugging conveniently, so the antenna standing wave also just can do relatively goodly, dropped to below 1.3 by 1.5 standing waves of original ceramic medium antenna.
