Problems solved by technology

[0004] However, in order to achieve the purpose of miniaturization, multiple antennas will be closely arranged, resulting in mutual interference
In order to increase the isolation between these antennas, a piece metal spacer is usually added between these antennas, however, the metal spacer can only increase the isolation within a certain range

Embodiment Construction

[0020] see figure 1 , which is a dual-frequency antenna structure 100 provided by an embodiment of the present invention. The dual-frequency antenna structure 100 can be installed on a wall or a ceiling, and can also be installed on devices including smart phones, tablet computers, mobile hotspots, and USB wireless transceivers. waiting for mobile devices. The dual-band antenna structure 100 includes a dielectric substrate 10 , a first group of antenna arrays 20 , a second group of antenna arrays 30 , two first bent isolation plates 40 and two second bent isolation plates 50.

[0021] The dielectric substrate 10 includes a first surface 13 and a second surface (not shown) disposed opposite to each other. The first surface 13 is provided with a plurality of corner regions 11 and a central region 12 . Conductive material (not shown) is printed on the second surface to form a ground plane. In this embodiment, the dielectric substrate 10 is substantially rectangular, that is, ...

Abstract

A dual-frequency antenna structure, comprising: a dielectric substrate, including a plurality of corner areas and a central area; a first group of antenna arrays located at the corner areas; a second group of antenna arrays located at the At the central area: at least one first bent isolation plate, the two first bent isolation plates are located on the dielectric substrate, and are located between the first group of antenna arrays and the second group of antenna arrays Between: at least one second bent isolation board, each second bent isolation board is mounted on one of the first bent isolation boards.

Description

technical field [0001] The present invention relates to the field of antennas, in particular to a dual-frequency antenna structure. Background technique [0002] MIMO (Multiple-Input Multiple-Output) technology refers to the use of multiple transmit and receive antennas at the transmitter and receiver, respectively, so that signals are transmitted and received through multiple antennas at the transmitter and receiver, thereby improving communication quality. It can make full use of space resources, realize multiple transmission and multiple reception through multiple antennas, and can double the system channel capacity without increasing spectrum resources and antenna transmission power, showing obvious advantages and being regarded as the next generation mobile phone. The core technology of communication. [0003] With the universal use of WIFI frequency bands around the world, the use of WIFI is becoming more and more frequent in our daily life, and we are also more and m...
