Problems solved by technology

Current notebooks are usually equipped with WLAN antennas, and some new models have added WWAN antennas, but due to the miniaturization requirements of notebooks, the space for placing antennas is limited, and because most of the current antennas are PCB (Printed Circuit Board, printed circuit board) antennas , the volume is large, so it is not possible to integrate WWAN+WLAN+Wimax (Worldwide Interoperability for Microwave Access) MIMO (Multiple-Input Multiple-Out-put) antennas in a small space
[0005] Therefore, the disadvantage of this solution is that it is not possible to support all the antenna modes currently required for small notebooks
[0007] The disadvantage of this solution is that the raw materials must be replaced. If you want to directly integrate the antenna on the notebook casing, you must use special materials to remake the casing, and then process the antenna on it.
Increased cost and process complexity

Abstract

The embodiment of the invention provides a miniature antenna of a laptop and a mobile electric apparatus, wherein the miniature antenna comprises a first antenna for providing antenna service of a first mode, a second antenna for providing antenna service of a second mode; the first mode is different from the second mode; and the grounding branch of the first antenna is coupled to a radiation branch of the second antenna. The embodiment of the invention can improve the performance of antenna in complicated environment and realize coexistence of multiple antenna systems in the laptop.

Description

technical field [0001] The invention relates to an antenna for a notebook computer, in particular to a miniaturized antenna for a notebook computer and a mobile electronic device. Background technique [0002] At present, the development trend of notebook computers is miniaturization, thinness and low cost. In the process of miniaturization, the configuration of wireless communication methods has become a headache for notebook manufacturers. This is because: with the increase in the number of antennas, various antennas The integration in small notebooks is becoming more and more difficult. Forcibly installing antennas of various modes will cause mutual coupling between the antennas and seriously reduce the performance of the antennas. [0003] In the process of realizing the technical solution of the present invention, it is found that the prior art has at least the following defects, [0004] Existing solution 1: WWAN (wireless WAN, wireless wide area network)+WLAN (wirele...
