Antenna and terminal

Abstract

Provided in the embodiments of the present invention and relating to the field of communications are an antenna and a terminal, the antenna comprising: a first antenna, a grounding unit, a ground wire and a second antenna; the grounding unit is positioned between the first and the second antennae but does not contact either antenna; one end of the grounding unit is connected to the ground wire; the grounding unit is symmetrical in structure and the axis of symmetry thereof is perpendicular to the ground wire; the first and the second antennae are connected respectively to the ground wire by corresponding electrical feed ports. The present invention utilizes two antennae in a small space and provides between said two antennae a symmetrical grounding structure; the isolation of each antenna from the other provides excellent complementarity of the two antenna patterns, enhances the degree of isolation and the correlation coefficient of the two antennae, and reduces the difficulty of antenna development.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an antenna and a terminal. Background technique [0002] With the development of wireless communication technology, wireless fidelity (abbreviated as WIFI in English, spelled as Wireless Fidelity in English) technology has been widely used, but the data card is generally relatively small, and the antenna area of ​​the data card with wireless fidelity function The effective space is relatively small, which makes the isolation and correlation coefficient between the input and output antennas poor. However, wireless communication has higher and higher requirements for the performance of the antenna. It is hoped that wireless protection can be achieved in a limited space. The true frequency band, and the indicators are better, especially the isolation and correlation coefficient, which increases the data card broadband multiple input multiple output (MIMO in English, s...

[0002] With the development of wireless communication technology, wireless fidelity (abbreviated as WIFI in English, spelled as Wireless Fidelity in English) technology has been widely used, but the data card is generally relatively small, and the antenna area of ​​the data card with wireless fidelity function The effective space is relatively small, which makes the isolation and correlation coefficient between the input and output antennas poor. However, wireless communication has higher and higher requirements for the performance of the antenna. It is hoped that wireless protection can be achieved in a limited space. The true frequency band, and the indicators are better, especially the isolation and correlation coefficient, which increases the data card broadband multiple input multiple output (MIMO in English, spelled in English as Multiple-Input Multiple-Out-put,) antenna design difficulty

[0003] In the prior art, in order to improve the isolation and correlation coefficient of the MIMO antenna in the WiFi frequency band of the data card, the MIMO antenna in the WiFi frequency band of the data card is usually composed of two distant monopole antennas , try to increase the distance between the two monopole antennas in a limited space to improve the isolation and correlation coefficient between the antennas. This solution increases the difficulty of antenna development
