1. Field of the Disclosure
The present disclosure relates generally to a multiple-input multiple-output (MIMO) technology for an antenna structure, and more particularly to an electronic device including the antenna structure.
2. Description of the Related Art
The advance of mobile communication and antenna technologies are accompanied by an increase of the number of antennas included in electronic devices. However, as electronic devices are generally small-sized, the available spaces for mounting the antennas is limited.
Further, because antennas are normally mounted in the limited interior spaces of the electronic devices, the antennas are often arranged very close to each other. Consequently, these neighboring antennas may interfere with each other, for example, when signals of adjacent frequencies are transmitted and received, thereby lowering of the performance of the antennas.
Additionally, when a housing of an electronic device is formed of a conductive material (for example, metal), the radiation performance of the antenna may also be affected.
