Abstract
The present invention relates to an antenna device, which includes a plurality of antenna elements, a plurality of ring-shaped slits formed therein, and an interference shielding element for transmitting and receiving signals introduced from the antenna elements along slits. According to the present invention, in operation of the antenna device, electromagnetic mutual coupling between the antenna elements is suppressed.
Description
The present invention relates to an antenna device, and more particularly to an antenna device having a plurality of antenna elements.
2. Description of the Related Art Generally, studies are being conducted to improve the performance of an antenna device in a communication terminal. This is because the antenna device in the communication terminal is responsible for substantially transmitting and receiving signals. Accordingly, recently, a multiple-input multiple-output (MIMO) antenna device has been proposed as an antenna device mounted on a communication terminal. At this time, the mimo antenna apparatus has a plurality of antenna elements. In such a fine antenna apparatus, signals are transmitted and received in a frequency band through the antenna elements, thereby being connectable to various communication networks.
However, there is a problem that electromagnetic coupling occurs between the antenna elements during operation of the mimo antenna apparatus as described above, resulting in deterioration of the performance of the communication terminal. This problem becomes more serious as the miniature antenna device is miniaturized. Therefore, there is a demand for a method for suppressing electromagnetic mutual coupling between antenna elements in a fine antenna apparatus.
Accordingly, the present invention provides an antenna device for suppressing electromagnetic mutual coupling between antenna elements. Furthermore, the present invention provides an antenna device for improving the performance of a communication terminal.
According to an aspect of the present invention, there is provided an antenna device including a plurality of antenna elements and a plurality of ring-shaped slits formed therein, the antenna elements transmitting signals received from the antenna elements along the slits, Device.
At this time, in the antenna device according to the present invention, any one of the slits is formed inside the other one of the slits.
In the antenna device according to the present invention, the interference shielding element may include a slit closing part for closing any one of the slits corresponding to one of the antenna elements.
In the antenna device according to the present invention, the interference shielding element is disposed between the antenna elements.
In operation of the antenna device according to the present invention, the electromagnetic mutual coupling between the antenna elements is suppressed. That is, the interference shielding element cancels the incoming signals from the antenna elements, thereby suppressing interference between the antenna elements. This improves the performance of the antenna device. Further, the performance of the communication terminal is improved. In addition, even if the antenna elements are disposed adjacent to each other in the antenna apparatus, the operation performance of the antenna apparatus can be ensured. Thus, it is possible to realize miniaturization of the antenna device. Furthermore, miniaturization of the communication terminal is possible.

On the other hand, in the above-described embodiments, an example in which the antenna device includes two antenna elements is described, but the present invention is not limited thereto. That is, even if the antenna apparatus includes three or more antenna elements, implementation of the present invention is possible. At this time, the antenna device may include one interference blocking element, and may include two or more interference blocking elements. For example, if the antenna device includes one interferer, the interferer can be placed at a spaced distance similar to all the antenna elements. At this time, the number of slits corresponding to the number of antenna elements may be formed in the interference shielding element. And the interference shielding element may include a number of slit closures corresponding to the number of slits. Here, the slit closing portions correspond to any one of the different ones in the antenna elements, so that the slits can be closed individually. Or when the antenna device comprises a plurality of interference shielding elements, each interference shielding element may be arranged between the two antenna elements.
According to the present invention, in operation of the antenna device, electromagnetic mutual coupling between the antenna elements is suppressed. That is, the interference shielding element cancels the incoming signals from the antenna elements, thereby suppressing interference between the antenna elements. This improves the performance of the antenna device. Further, the performance of the communication terminal is improved. In addition, even if the antenna elements are disposed adjacent to each other in the antenna apparatus, the operation performance of the antenna apparatus can be ensured. Thus, it is possible to realize miniaturization of the antenna device. Furthermore, miniaturization of the communication terminal is possible.
