Abstract
The utility model discloses a signal receiving performance enhancing structure of a navigation antenna. The signal receiving performance enhancing structure comprises the navigation antenna, wherein the navigation antenna mainly consists of an upper cover, a base shell, an antenna amplifier, a shielding cover, a ceramic radiating body and a coaxial radio frequency cable; and the signal receiving performance enhancing structure is characterized in that a metal reflection layer is arranged at the surface of the base shell and taken as a reflection face of the ceramic radiating body. According to the signal receiving performance enhancing structure of the navigation antenna, the structure is simple, the passive gain of the antenna in a zenith direction can be improved, the refracted and reflected signal interferences are reduced, and the signal receiving performance enhancing structure of the navigation antenna has a good promotional value.
Description
Technical field
The utility model relates to antenna technical field, especially relates to a kind of structure that is installed on the raising received signal strength of built-in GPS on the automobile window glass or Big Dipper navigation antenna.
Background technology
At present, fast development along with auto industry, people are that requirement is more and more higher to the technology of automobile each side, navigator also becomes the common outfit product of automobile, the common installation position of navigation antenna is equipped with multiple choices, having a kind of is to stick near the centre rear-view mirror of front windshield in the car, and this kind mounting means is affected the decay of navigation satellite signal and the multipath effect of satellite-signal etc. by vehicle glass, can cause searching the star effect and descend.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of simple in structure, can improve antenna without source gain, and the signal receiving performance that reduces to reflect the navigation antenna that reflected signal disturbs strengthens structure.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of signal receiving performance of navigation antenna strengthens structure, comprise the navigation antenna that is mainly consisted of by loam cake, drain pan, antenna amplifier antennafire, screening cover, ceramic radiation body and coaxial radio frequency cable, it is characterized in that, described drain pan surface is provided with metallic reflector, as the reflecting surface of ceramic radiation body.
As further specifying of such scheme, the shape of described metallic reflector is consistent with the drain pan surface.
Be provided with screens on the described drain pan, the antenna amplifier antennafire circuit board is installed on the metallic reflector by this screens.
Described ceramic radiation body welded and installed forms angle of inclination and ultrasonic bonding fusion between loam cake and the drain pan on the circuit board of antenna amplifier antennafire.
Cover on described and cover a Double-side foam celloidin, when antenna sticked on the glass for vehicle window by sandwich rubber according to the glass cambered surface, the ceramic radiation body was towards zenith direction, and metallic reflector is positioned at its below as the reflecting surface of ceramic radiation body.
Described metallic reflector is in the drain pan or the metal bisque of outer surface spraying.
Described metallic reflector is the layer of metal film in drain pan inner surface or outer surface stickup.
Described metallic reflector is at the endosexine of drain pan or extexine.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts large tracts of land that the layer of metal reflector is set and uses as the navigation antenna reflecting surface, can significantly improve the navigation satellite signal intensity that navigator receives, and greatly improves carrier signal and noise signal power spectral density ratio (C/No); At weak signal area (under the overpass, intensive high building place), the cold start-up time is reduced in the quick location that can realize navigator especially.
