Abstract

The invention provides an annular loop closed metal ring antenna. The annular loop closed metal ring antenna comprises a feed wire and a closed meal ring side frame; the feed wire is electrically connected with a circuit board through a feed point and electrically connected with the closed metal side frame through a connecting point; two side edges of the closed metal ring side frame are respectively electrically connected to reference ground at the corresponding side edge of the circuit board through a first grounding point and a second grounding point; the fed wire, the closed metal ring side frame and the circuit board form first and second clearance areas; each of the first and second clearance areas comprises clearances which are formed between two side edges of the circuit board and the corresponding side edge of the closed metal ring side frame; the feed point enters the first and second clearance areas of the first and second grounding points through the connecting point to form first and second annular loops which have different resonance length. Compared with the traditional antenna, the antenna has the advantages that the bandwidth is expanded, the performance is improved, and the bandwidth design is highly flexible to adjust.

Description

technical field [0001] The invention relates to antenna technology, in particular to a ring loop closed metal loop antenna and a mobile device. Background technique [0002] With the rapid development of information and communication technology and the electronic industry, mobile communication devices with various functions have become one of the necessities of modern people. The antenna installed on the mobile communication terminal equipment has experienced the development from 2G to 4G-LTE, and the antenna needs to carry more and more frequency bands. In contrast to the current trend of large screens and thinner devices, more manufacturers prefer to use closed metal ring frames to provide the strength, texture and beauty of the device structure. However, this metal frame makes the gradually narrowing antenna area smaller, making it difficult for current conventional antennas to achieve desired wireless performance. Contents of the invention [0003] The main purpose o...
