Problems solved by technology

Therefore, the traditional antenna is not conducive to the trend of thin and short mobile phones. In addition, because of the large size of the antenna, the above-mentioned metal electronic components may not be able to avoid the position of the antenna, which will interfere with the antenna and affect the quality of reception.

Embodiment Construction

[0029] First, please refer to Figure 2A , Figure 2A is a plan view of the antenna module 200 provided by the embodiment of the present invention. The antenna module 200 includes a metal ground plane 201 , a signal feed-in portion 202 , a ground portion 203 and a first asymmetric meander line 204 . Wherein the ground part 203 is connected to the metal ground plane 201, and the ground part 203 may be a short-circuit wire. One end of the first asymmetric meandering line 204 is connected to the signal feeding part 202 , and the other end is connected to the ground part 203 , and the first asymmetrical meandering line 204 does not meander toward the inner wall.

[0030] It should be noted here that the first asymmetric meandering line 204 can reduce the required area of ​​the antenna module 200, and can also generate an inductive effect to offset the capacitive effect existing in the antenna module 200, thereby improving the antenna radiation efficiency. In this embodiment, a...

Abstract

The invention relates to an antenna module and an electronic device applying the same. The antenna module is provided with a signal feed-in part, a grounding part and a first asymmetric winding line, wherein one end of the first asymmetric winding line is connected to the signal feed-in part; the other end of the first asymmetric winding line is connected to the grounding part; the first asymmetric winding line is not winding towards the inner wall; a signal is fed in by the signal feed-in part; and a first resonant mode frequency is stimulated by the first asymmetric winding line. The area of the antenna module provided by the invention is less than that of traditional panel antennas, and the antenna module can generate inductive effect so as to improve the radiation efficiency of the antenna. In addition, because the area of the antenna module is smaller, a metal electronic component in the electronic device can not be overlapped with a position of the antenna module so as to reducethe chance of mutual interference.

Description

technical field [0001] The present invention relates to an antenna module and an electronic device for its application, and in particular to a small-area antenna module and an electronic device for its application. Background technique [0002] In recent years, with the rapid development of the global handheld wireless communication industry, mobile phones have changed from early dual-band (for example: Global System for Mobile communications 900 (GSM900) / Digital Cellular System (DCS)) The use of simple call function, and to tri-band (for example: GSM900 / DCS / personal communication service system (Personal Communications Service, PCS)), and even evolved to quad-band (for example: GSM900 / DCS / PCS / Wideband Code Division Multiple Access System ( Wideband Code Division Multiplex Access, WCDMA)) video call function. Since the functions of mobile phones are gradually oriented toward audio-visual entertainment, such as taking pictures, listening to digital music, wireless network, G...
