Embodiment Construction

[0029] An antenna for a mobile terminal proposed by the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims.

[0030] An antenna for a mobile terminal provided by the present invention includes: a first branch 1, a second branch 2, a third branch 3, a fourth branch 4, a fifth branch 5, a first ground port 6, a second ground port 8, a feeder Electrical port 7. The first branch 1, the second branch 2, the third branch 3, the fourth branch 4, the first ground port 6, and the feed port 7 together form the antenna of the IFA wiring; and the fourth branch 4, the fifth branch 5, the The two grounding ports 8 and the feeding port 7 together form the antenna of the MINI-L00P wiring.

[0031] Specifically, such as image 3 As shown, the second branch 2 is connected to the first branch 1; one end of ...

Abstract

The invention discloses an antenna for a mobile terminal. IFA wire arrangement and LOOP wire arrangment are adopted for the antenna at the same time, and a MINI-LOOP antenna and an IFA antenna share afeeding port. On one hand, antenna space can be saved, the IFA antenna and the MINI-LOOP antenna share one face, and an original size for two antennas is reduced to a size for one antenna; one the other hand, a large high frequency radiation current can be successfully pulled to one side of MINI-LOOP via MINI-LOOP trace, antenna radiance in high frequency 2300 MHz-2690 MHz bandwidth can be improved, a radiation arm on one side of IFA is assisted via a radiation arm on one side of MINI-LOOP, low frequency radiation effects and angles can be improved, and low frequency band width can be enlarged.

Description

technical field [0001] The invention belongs to the field of antenna design, and in particular relates to an antenna for a mobile terminal. Background technique [0002] With the development of terminal mobile phones, in order to adapt to consumers' aesthetics, mobile phones with full screens have become mainstream. Its small headroom design poses challenges for mobile phone antennas. [0003] When designing traditional mobile phone antennas, antennas with IFA wiring are often used, such as figure 1 As shown, or the antenna design of the LOOP trace, such as figure 2 shown. However, these two antennas often encounter various problems in the debugging of full-screen mobile phones. The IFA antenna has high requirements for headroom, and in a small headroom environment, its resonance is difficult to get out, and its efficiency is low. The LOOP antenna is a type of volume multiplexing antenna, which requires a relatively large area, and is often limited by the structure in ...
