Embodiment Construction

[0035] In order to make the above and other objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention are listed below and described in detail in conjunction with the accompanying drawings.

[0036] Certain terms are used in the description and claims to refer to particular elements. It should be understood by those skilled in the art that hardware manufacturers may use different terms to refer to the same element. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that a first device is coupled to a second de...

Abstract

The invention discloses a mobile communication device, comprising an antenna structure, wherein the antenna structure is provided with a grounding element and an antenna element. The antenna element comprises an antenna grounding surface, a radiation part and a short-circuit radiation part, wherein the antenna grounding surface is electrically connected with the grounding element. The radiation part comprises a signal feeder point, a first radiation branch path and a second radiation branch path. The first radiation branch path and the second radiation branch path are connected with the signal feeder point; the opening ends of the first radiation branch path and the second radiation branch path extend in the same direction. The first end of the short-circuit radiation part is in electric short circuit to the antenna grounding surface, and the second end of the short-circuit radiation part is an opening end; a coupling distance exists between a special section of the short-circuit radiation part, close to the first end and the radiation part; the short-circuit radiation part is coupled and excited by the radiation part by the coupling distance to generate at least one resonance mode so as to increase the operation bandwidth of the antenna.

Description

technical field [0001] The invention relates to a mobile communication device and its antenna structure, in particular to a mobile communication device whose built-in antenna has shielding metal walls and multi-frequency operating frequency bands. Background technique [0002] With the rapid development of wireless communication technology, it has prompted the birth of Long Term Evolution (LTE, Long Term Evolution) mobile communication technology, which means that mobile communication device antennas will require lower operating frequencies and wider bandwidths. It includes about 704-960 MHz and 1710-2690 MHz to cover the tri-band operation of LTE700 / 2300 / 2500 and the five-band operation of WWAN (Wireless Wide Area Network). While portable communication devices demand thin, small and multi-frequency operation, the space for accommodating antennas is relatively reduced. Therefore, the miniaturization technology of built-in multi-frequency antennas in communication devices is ...
