Abstract

A communication device comprises a grounding element and an antenna element. The antenna element has a first connection point, and at least comprises a first branch, a second branch and a third branch. One end of the first branch is coupled to the first connection point via an inductance element. One end of the second branch is coupled to the first connection point. A second section of the second branch is roughly parallel to a first section of the first branch. The second branch is arranged between the first branch and an edge of the grounding element. One end of the third branch is coupled to a second connection point on the first branch. The third branch and the first branch extend in roughly opposite directions. The first connection point is also coupled to a signal source via a high-pass matching circuit. A grounding end of the high-pass matching circuit is coupled to the grounding element. The antenna element of the communication device provided by the invention can be designed to be low in posture and small in size, and the antenna element can carry out operation in multiple bands including LTE/WWAN band and WLAN2.4GHz band.

Description

technical field [0001] The present invention relates to a communication device, in particular to a communication device including a small-sized multi-branch multi-band antenna element (Small-size Multi-branch Multi-band Antenna Element). Background technique [0002] Mobile communication technology is changing with each passing day, and its role in human life is getting heavier and heavier. Due to the different communication technologies in different eras and the different operating frequency bands of telecom operators in different regions, the demand for bandwidth of mobile communication devices is also increasing day by day. To facilitate portability and improve user experience, today's mobile communication devices tend to be thinner and lighter overall, and the size of their screens and frames will become smaller, and the space available for designing antennas will become less and less. Taking the traditional multi-branch multi-band LTE / WWAN (Long Term Evolution / Wireless...
