A loop antenna and related electronic equipment

Abstract

Disclosed are a loop antenna and a related electronic apparatus which can effectively broaden the high frequency bandwidth and improve the agility of antenna routing and the adjustability of the antenna. The embodiments of the present invention include: a feed point of a positive antenna and a feed point of a grounding antenna, wherein the feed point of the positive antenna or the feed point of the grounding antenna is connected with a monopole antenna; the feed point of the positive antenna is connected with a first conductive component, and is connected with the feed point of the grounding antenna via the first conductive component, wherein the first conductive component is a part of the periphery conductive frame of the electronic apparatus having the loop antenna.

Description

technical field [0001] The present invention relates to the technology in the communication field, in particular to a loop antenna and related electronic equipment. Background technique [0002] The antennas of the original handheld communication devices (such as mobile phones, tablet computers, etc.) only support the Global System for Mobile Communications (GSM, global system for mobile communications) standard. The number of antennas of the mobile communication device enables the handheld communication device to simultaneously support the third generation mobile communication technology (3G, 3rd-generation), 4G, wireless fidelity, global positioning system and other network standards. [0003] Taking mobile phones as an example, now usually a smart phone needs to design 4 to 6 or even more antennas. At the same time, consumers' demand for small and thin mobile phones has been increasing, and manufacturers have been working to improve antenna design with compact structures...

Problems solved by technology

[0004] However, the loop antenna routing designed by the metal frame structure is fixed and relatively simple, and the adjustability is weak. It is difficult to excite multiple high-frequency resonances only by the metal frame from the antenna feed point to the ground plane, which is likely to cause high The frequency bandwidth is insufficient, and the metal frame is used as the antenna radiator. The maximum electric field of high and low frequency resonance is on the metal frame, and the metal frame slits are set at the left and right frames, which is likely to cause serious deterioration of the antenna performance when holding it.
