Antenna applicable to global satellite positioning system

Abstract

The invention relates to an antenna applicable for a global satellite positioning system (GPS). The antenna comprises an earthed sheet metal, a parasitic sheet metal, a radiation sheet metal and at least one supporting element. The parasitic sheet metal is arranged above the earthed sheet metal and connected with the earthed sheet metal. The radiation sheet metal is a separate sheet metal arranged above the earthed sheet metal and matched with the parasitic sheet metal in order to produce a resonance mode. The supporting element is arranged on the earthed sheet metal for supporting the radiation sheet metal, thereby solving the problems that the antenna of the routine circular polarization GPS has large size and small receiving angle.

Description

technical field [0001] The present invention relates to an antenna applied to a wireless network, in particular to an antenna applied to a Global Positioning System (GPS). Background technique [0002] With the vigorous development of wireless communication technology, various multi-frequency communication products have sprung up, and therefore wireless communication products have gradually become a part of human life. Almost all new products will have the function of wireless transmission to meet The needs of the public, while notebook computers or mobile multimedia devices usually require data transmission, wireless transmission can simplify many of its wiring and setting troubles, and in order to achieve the purpose of wireless transmission, the configuration of the antenna becomes necessary. If a notebook computer or mobile multimedia device with wireless transmission function wants to be widely accepted and affirmed by the market, the appearance, size and performance of...

Problems solved by technology

However, conventional circularly polarized global satellite positioning system antennas have more space constraints, and it is really difficult to apply to smaller products (such as notebook computers), so the application range is relatively limited

[0004] In addition, the electromagnetic field type of the conventional circularly polarized global satellite positioning system antenna belongs to right-handed polarization, so its receiving angle for the signal transmitted by the satellite is limited to the top of the conventional circularly polarized global satellite positioning system antenna (about 15 degrees angle range), but lacks the signal receiving capability of the side, so there will be more receiving dead angles
