Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as Figure 1 to Figure 3 As shown, an antenna structure 100 for an LTE full-band mobile phone includes a ground plane 102 , a circuit board (not shown) with a feed point, and a metal unit surrounding the circuit board and the ground plane 102 . In the present invention, the metal unit is the metal frame 101 of the mobile phone.

[0021] The metal frame 101 is rectangular with four sides. The ground plate 102 has the same shape as the metal frame 101, which has a pair of short sides and a pair of long sides. A gap 104 is provided between one of the short sides 102A and one of the shorter sides of the metal frame. There are two parallel and spaced slits 101B on the shorter side, the part between the two slits 101B is the non-grounded part 101A electrically connected to the feed point on the ground plate, and the rest of the metal frame 101 ...

Abstract

The invention provides an LTE full band mobile phone antenna structure, which comprises a grounding board, a circuit board provided with a feed point, a feed-end matching circuit arranged on the circuit board and a metal unit arranged around the circuit board and the grounding board, wherein the metal unit comprises a grounding part electrically connected with the grounding board and a non-grounding part electrically disconnected with the grounding part; the feed point is electrically connected with the non-grounding part such that the non-grounding part serves as a medium-high frequency radiator; a gap is arranged between the non-grounding part and the grounding board, the grounding board is excited to generate current in a coupling mode via the gap, and the grounding board serves as a low-frequency radiator. The non-grounding part of the metal unit serves as the medium-high frequency radiator, the non-grounding part and the grounding board are coupled such that the grounding board serves as the low-frequency radiator, the feed-end matching circuit is added to the feed end on the basis, the antenna can cover all bands of the LTE, and the LTE full band mobile phone antenna structure has the advantages that the debugging difficulty is low, and influences from the processing precision is little.

Description

【Technical field】 [0001] The invention relates to the field of mobile communication, in particular to an LTE full-band mobile phone antenna structure of a mobile electronic device. 【Background technique】 [0002] Antennas are used to transmit or receive radio waves to transmit or exchange radio signals. Generally, electronic products with wireless communication functions, such as mobile phones, personal digital assistants, notebook computers, etc., usually access wireless networks through built-in antennas. At present, electronic products with full metal frame are more and more popular among consumers. [0003] Most mobile phone antennas in the related art use metal frames with breakpoints as radiators, and besides, there are one or more radiators in the form of FPC or LDS. However, FPC or LDS antennas also have some problems, for example, it is difficult to debug the antenna pattern, and there are frequency offsets caused by processing accuracy tolerances. [0004] There...
