Problems solved by technology

However, it is precisely because of the small size and high integration of communication equipment that the space for antenna installation is narrow and the clearance area required by the antenna is insufficient, which makes the antenna easily interfered by peripheral circuits. 5G technology communication equipment is also compatible with 2 / 3 / 4G functions, which makes the available space for the antenna inside the communication equipment less and less, which also leads to a very limited frequency band and bandwidth that the antenna can support

Abstract

The invention discloses an antenna assembly and a mobile terminal. The antenna assembly comprises a metal frame, a matching circuit, an antenna wire and a tuning module. The metal frame is provided with a feed point, and the matching circuit is connected with the feed point on the metal frame. One end of the antenna wire is connected with the feed point, and the other end of the antenna wire is connected with the tuning module; the antenna wiring is arranged between the tuning module and the matching circuit, the antenna wiring and the metal frame achieve shunting, the circulation distance ofcurrent between the tuning module and the feed point is equivalently shortened, and therefore the tuning range and bandwidth width are improved. The connection of the antenna wiring and the tuning module is equivalent to the addition of an impedance-adjustable parallel circuit at the feed point, thereby playing a role in impedance tuning, reducing the return loss of the antenna, and improving theresonant frequency range of the antenna while guaranteeing the transmission efficiency of the circuit.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an antenna assembly and a mobile terminal. Background technique [0002] In the field of mobile communication, as an important part of the wireless signal transmission and reception link, the performance of the antenna plays a vital role in the communication capability of a mobile communication device. The combined configuration of metal frame and full screen has become a major trend in today's mobile communication equipment, and modern communication equipment not only needs to have the characteristics of small size, high integration and mobility, but also in order to make the appearance of the product more beautiful. Therefore, the use of built-in antennas is most in line with the design trend of wireless applications. However, it is precisely because of the small size and high integration of communication equipment that the space for antenna installation i...
