FIELD OF THE PRESENT DISCLOSURE

The invention relates to the field of communication technologies, in particular to a mobile terminal and a glass housing thereof, and a performance optimization method of an antenna module of the mobile terminal.

DESCRIPTION OF RELATED ART

5G serves as a development and research focus in the industry all over the world and development of 5G technology and formulation of 5G standard have become consensus in the industry. International Telecommunication Union ITU has explicated three major application scenes of 5G: enhanced mobile broadband, large scale machine communication and high reliability low delay communication in the 22th session of ITU-RWP5D held in June, 2015. The three application scenes correspond to different key indexes, separately. The peak velocity of a user in the enhanced mobile broadband scene is 20 Gbps and the lowest user experience rate is 100 Mbps.

3GPP is standardizing the 5G technology. The first 5G NSA national standard has been accomplished and frozen in December, 2017. 5G independent networking standard has been accomplished on 14th, Jun., 2018.

Rich bandwidth resources of millimeter wave frequency bands guarantee the high speed transmission rate. However, it is needed to adopt an architecture of a phased array by a wireless communication system using the millimeter wave frequency bands due to several spatial loss of electromagnetic waves in the frequency bands.

An antenna serves as indispensable parts in a radio frequency front end system. System integration and packaging on the antenna and a radio frequency front end circuit become an inevitable trend of development of future radio frequency front ends while the radio frequency circuit develops toward integrated and miniaturized directions. Antenna-in-Package (AiP) technology integrating the antenna in a package carrying a chip by means of a packaging material and a packaging process gives consideration of antenna performance, cost and volume well, and is highly appreciated by wide chip and package manufacturers. At present, companies such as Qualcomm, Intel and IBM adopt the AiP technology. It is no doubt that the AiP technology will provide a good antenna solution for 5G millimeter wave mobile communication system.

As far as 5G millimeter wave frequency band is concerned, 3GPP provides several standard working frequency bands: n257 (26.5 GHz-29.5 GHz), n258 (24.25-27.5 GHz), n260 (37-40 GHZ) and n261 (27.5-28.35 GHZ). When the millimeter wave antenna module is mounted in the 3D glass housing, the glass housing has certain influence on radiation performance of the antenna module.

Therefore, it is necessary to provide an improved glass housing which improves the radiation performance of an antenna module of a mobile terminal.

SUMMARY OF THE INVENTION

One of the main objects of the present invention is to provide a glass housing of a mobile terminal with an antenna module having improved performance.

Another main of the present invention is to provide an optimization method to improve the performance of the antenna module of the mobile terminal.

In order to achieve the objects mentioned above, the present invention provide a glass housing of a mobile terminal with an antenna module, comprising: a radiation zone facing the antenna module and a non-radiation zone adjacent to the radiation zone; wherein the glass shape of the radiation zone and the glass shape of the non-radiation zone are of discontinuity.

In addition, the shapes of at least one side surface of the glass in the radiation zone and one side surface of the non-radiation zone are of discontinuity.

In addition, the glass in the radiation zone and the non-radiation zone have outer surfaces with continuous shapes, and the inner surface of the radiation zone is sunken toward the outer surface compared with the inner surface of the non-radiation zone.

In addition, the glass in the radiation zone and the non-radiation zone have inner surfaces with continuous shapes, and the outer surface of the radiation zone is sunken to the inner surface compared with the outer surface of the non-radiation zone.

In addition, the glass in the radiation zone is lens-shaped.

In addition, the radiation zone is located on the side edge or at the bottom of the glass housing, and the bottom of the glass housing is opposite to a display screen of the mobile terminal.

The present invention also provides a mobile terminal, comprising an antenna module and the glass housing as described above, wherein the glass housing covers the antenna module externally.

In addition, the antenna module faces the side edge or the bottom of the glass housing, and the bottom of the glass housing is opposite to the display screen of the mobile terminal.

The present invention further provides a performance optimization method of an antenna module, comprising steps of: providing a glass housing covering the antenna module externally; and optimizing the performance of the antenna module by changing a shape of a zone of the glass housing facing the antenna module.
