Problems solved by technology

[0004] At present, most antenna designs of mobile terminals support 2CA within a frequency band or between frequency bands, that is to say, the antenna of the mobile terminal can use up to two carriers for uplink and downlink transmission at the same time, but the communication transmission rate of this antenna is slow

Embodiment Construction

[0054] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0055] Such as Figure 1 to Figure 3 As shown, the embodiment of the present invention provides an antenna, which can be applied to mobile terminals such as mobile phones and tablets. The antenna includes a metal middle frame, a main board 15 and a ground feeding port 17 , a feeding port 16 and a tuning switch 18 arranged on the main board 15 .

[0056] The above-mentioned metal middle frame is a metal middle frame of a mobile terminal, and the metal middle frame may have a two-stage structure, and the two-stage metal middle frame includes a radiation frame 10 and a ground frame 11 which are arranged separately. The radiating frame 10 can be used as a radiating part of the antenna, specifically, the radiating frame 10 includes a first radiating part 100 and a second radiating part 101 . The ground frame 11 can be directly el...

Abstract

The invention relates to an antenna and a mobile terminal. The antenna includes a metal middle frame with a radiation frame and a ground frame separately arranged, a main board, a ground feed port, a feed port, and a tuning switch arranged on the main board, and first gaps are respectively formed at opposite ends of the radiation frame and the ground frame and the second slot, the feed port, the ground feed port and the tuning switch are all electrically connected to the radiation frame, the tuning switch is located between the ground feed port and the first slot, the feed port is located between the ground feed port and the second slot, and the radiation The part extending from the feed port to the first slot on the frame is the first radiation part, the part extending from the feed port to the second slot on the radiation frame is the second radiation part, and the working frequency band covered by the first radiation part includes the first The working frequency band and the second working frequency band, the working frequency band covered by the second radiation part includes a third working frequency band which is smaller than the first working frequency band and greater than the second working frequency band. This design can improve the communication transmission rate.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to an antenna and a mobile terminal. Background technique [0002] With the rapid development of communications, mobile terminals have become an indispensable tool in people's lives. In order to obtain better appearance design and hand-held feeling, metal shells are increasingly used in the design of mobile terminals. Terminal manufacturers' control of the length and thickness of mobile terminals, as well as the use of metal casings will occupy the space of the antenna to a certain extent, and put forward higher requirements for the design of the antenna. [0003] In order to meet the requirements of single-user peak rate and system capacity improvement, LTE-advanced (Long Term Evolution-advanced, long-term evolution technology upgrade version) introduces CA (Carrier Aggregation, carrier aggregation) technology to increase the transmission bandwidth of the antenna. CA techn...
