Problems solved by technology

[0005] In the related technology, since the 28GHz and 39GHz frequency bands are far apart, the package antenna cannot cover the two frequency bands, so the 28GHz frequency band and the 39GHz frequency band are two independent channels, which need to occupy a large area in the mobile phone space

Embodiment Construction

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. .

[0031] Such as Figure 1-3 As shown, the present invention provides a mobile terminal 100. The mobile terminal 100 may be a mobile phone, an ipad, and a POS machine, etc., and the present invention is not limited thereto. A back cover 2 that cooperates with the screen 1 to form a storage space, a main board 3 sandwiched between the screen 1 and the back cover 2 , and a packaged antenna system 4 connected to the main board 3 . Both the main board 3 and the packaged antenna system 4 are accommodated in the accommodation space.

[0032] The back cover 2 is a 3D glass back cover, which can provide better protection, aesthetics, thermal diffusion, color an...

Abstract

The invention provides a package antenna system and a mobile terminal. The mobile terminal includes a main board. The package antenna system includes a substrate, a metal antenna disposed on one sideof the substrate away from the main board, an integrated circuit chip disposed on one side of the substrate adjacent to the main board and a circuit disposed in the substrate and connected with the metal antenna and the integrated circuit chip. The circuit is connected to the main board, the metal antenna is a patch antenna, and the patch antenna is simultaneously fed by two feeding points. The two feeding points are used for exciting electromagnetic waves in different frequency bands. The package antenna system achieves dual frequency coverage of 28 GHz and 39 GHz. At the same time, the sizeis reduced to 18*5 mm, the occupied area is greatly reduced, and the gain reduction is small.

Description

【Technical field】 [0001] The invention relates to the technical field of wireless communication, in particular to a packaged antenna system and a mobile terminal. 【Background technique】 [0002] As 5G is the research and development focus of the global industry, it has become an industry consensus to develop 5G technology and formulate 5G standards. At the 22nd meeting of ITU-RWP5D held in June 2015, the International Telecommunication Union ITU clarified three main application scenarios of 5G: enhanced mobile broadband, large-scale machine communication, and high-reliability and low-latency communication. These three application scenarios correspond to different key indicators. In the enhanced mobile bandwidth scenario, the user peak speed is 20Gbps, and the minimum user experience speed is 100Mbps. At present, 3GPP is standardizing 5G technology. The first 5G non-independent networking (NSA) international standard was officially completed and frozen in December 2017, and ...
