Abstract

The invention discloses a double-frequency and double-polarization antenna capable of operating in a compass satellite navigation system and a mobile third-generation (3G) network and is implemented in a form of a laminated micro-strip circuit. The double-frequency and double-polarization antenna capable of operating in the compass satellite navigation system and the mobile 3G network comprises an upper-layer micro-strip antenna, a lower-layer micro-strip antenna and a metal floor layer, wherein the upper-layer micro-strip antenna has an upper-layer patch; the lower-layer micro-strip antenna has a lower-layer patch; the metal floor layer is arranged on a bottom layer; the upper-layer micro-strip antenna and the lower-layer micro-strip antenna share one metal floor layer; and the antenna is provided with six short-circuit metal columns which pass through the upper-layer micro-strip antenna and the lower-layer micro-strip antenna from the upper-layer patch and then are connected with the metal floor layer which is arranged on the bottom layer. The antenna adopts a feeding mode of dual-port coaxial feeding and has the advantages of simple and compact structure, miniaturization, convenience for processing and industrialized application, and the like.

Description

technical field [0001] The invention relates to an antenna, in particular to a dual-frequency dual-polarization antenna which can work in Beidou satellite navigation system and mobile 3G. Background technique [0002] With the development of satellite navigation technology and mobile Internet technology, applications based on location services are emerging. The main application in the domestic market is to obtain geographic location information with Beidou satellite navigation and positioning system, and to provide mobile Internet access services with GPRS and 3G networks. Therefore, the technical integration of Beidou satellite navigation and positioning system and the third-generation mobile communication technology TD-SCDMA It can better realize the mobile, location and real-time mobile Internet environment. Multi-system navigation (compatible) antennas that can simultaneously use Beidou satellite navigation and positioning system and mobile 3G signals will be more and m...
