Abstract

The invention belongs to the technical field of communication, and especially relates to an LTE multi-frequency-band antenna and a mobile terminal. The LTE multi-frequency-band antenna comprises an antenna main body part, a first branch part and a second branch part; the antenna main body part is provided with a feeding point (101) and a first grounding point (102), and a first high-frequency band is covered through resonance; the first branch part and the antenna main body part are spaced by a first gap, the antenna main body part performs coupling feeding through the first gap, and is resonant at a first resonance frequency point (f1) to cover a first low-frequency band; and the second branch part and the antenna main body are spaced by a second gap, the antenna main body performs coupling feeding through a second gap, and is resonant at a second resonance frequency point (f2) to cover a second low-frequency band. The technical scheme adopts a double coupling feeding mode, the antenna bandwidth can be effectively increased, an antenna resonance main body is relatively clear, and antenna analyses and debugging are easy.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a multi-band antenna. Background technique [0002] Today, with the rapid development of mobile communication technology, mobile phone terminals, as an indispensable device in people's lives, have increasingly demonstrated their powerful advantages and greatly improved people's life efficiency. Mobile phone antennas are indispensable in communication systems. The excellent performance of the antenna directly determines the performance of the entire mobile phone system. With the continuous enrichment of mobile phone functions, new requirements are put forward for the design of mobile phone antennas. Especially with the large-scale commercialization of 4G (the4thgenerationcommunicationsystem, fourth-generation mobile communication technology) LTE (LongTermEvolution, long-term evolution) network, mobile terminals are required to support traditional 2G (the2ndGener...
