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 application discloses an antenna component and a mobile terminal. The antenna assembly includes a metal frame, a matching circuit, antenna wiring and a tuning module; a feed point is provided on the metal frame, and the matching circuit is connected to the feed point on the metal frame; the antenna wiring One end of the antenna wire is connected to the feed point, and the other end of the antenna wire is connected to the tuning module; the antenna wire is set between the tuning module and the matching circuit, and the antenna wire and the metal frame are shunted, which is equivalent to shortening The distance between the current flowing between the tuning module and the feed point is increased, thereby improving the tuning range and bandwidth. At the same time, the connection between the antenna wiring and the tuning module is equivalent to adding a parallel circuit with adjustable impedance at the feed point. Play the role of impedance tuning, thereby reducing the return loss of the antenna, while ensuring the transmission efficiency of the circuit, it can also improve the resonant frequency range of the antenna.

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...
