Slot antenna and intelligent terminal

Abstract

Disclosed is a slot antenna. The slot antenna comprises a low frequency antenna and a high frequency antenna disposed separately. The low frequency antenna and the high frequency antenna have a feeder line, an impedance matching network, and a feeding point, respectively. The feeder line of the low frequency antenna is electrically connected to the impedance matching network and the feeding point of the low frequency antenna. The feeder line of the high frequency antenna is electrically connected to impedance matching network and the feeding point of the high frequency antenna. The high and low frequency antennas may be disposed on the surface layer and / or bottom layer of a printed circuit board (PCB), respectively. Further disclosed is a smart terminal. By adopting the technical solution of the present invention, the performance of high and low frequency radiation of an antenna is enhanced, and at the same time the work requirement of a carrier aggregation technology and the volume requirement of a smart terminal are met.

Description

technical field [0001] The invention relates to antenna technology, in particular to a slot antenna and an intelligent terminal. Background technique [0002] With the rapid development of communication technology, multi-mode coexistence is an inevitable trend in the development of smart terminals. In order to provide users with higher-quality broadband data services, antennas of smart terminals need to work in a wider frequency range. In the existing technical standards, the frequency ranges of various systems are different, such as: the frequency range of LTE low frequency band is 698MHz to 787MHz, the frequency range of LTE high frequency band is 2500MHz to 2690MHz, the frequency range of GSM / UMTS850 is 824MHz to 894MHz, GSM900 The frequency range of / UMTS900 is 880MHz to 960MHz, the frequency range of DCS1800 is 1710MHz to 1880MHz, the frequency range of PCS / UMTS1900 is 1850MHz to 1990MHz, the frequency range of UMTS2100 is 1920MHz to 2170MHz, etc. In addition, due to ...

AI Technical Summary

Problems solved by technology

[0004] At present, in order to obtain a wider bandwidth, the antenna of the smart terminal usually adopts the antenna form of a monopole and a coupled parasitic element, but it is still difficult for this type of antenna to cover the aforementioned full-frequency bandwidth

Other broadband technologies, such as microstrip slot antennas, non-frequency variable broadband antennas, etc., often only meet the requirements of high frequency bands, but it is difficult to obtain good low frequency characteristics at the same time
