Embodiment Construction

[0015] figure 1 is a schematic structural diagram of the antenna 100 according to a preferred embodiment of the present invention. The antenna 100 includes an antenna unit 101, and also includes a metamaterial panel 102 with a deflection function, and the metamaterial panel 102 is relatively arranged on the electromagnetic wave propagation direction d of the antenna unit 101 (such as figure 1 indicated by the arrow in).

[0016] Wherein, the specific structure of the metamaterial panel 102 is as follows figure 2 shown. Depend on figure 2 It is well known that the metamaterial panel 102 is composed of at least one metamaterial sheet. When there are multiple metamaterial sheets, they are stacked in a direction perpendicular to the surface of the sheet and form a three-dimensional whole through certain assembly or connection methods.

[0017] like figure 2 As shown, each sheet layer includes a sheet-shaped substrate 2 and a plurality of artificial microstructures 3 attach...

Abstract

The invention relates to an antenna, comprising an antenna unit and a metamaterial panel which has a deflection function and is used to deflect incident electromagnetic waves. The metamaterial panel is disposed opposite to the antenna unit on a propagation direction of the electromagnetic waves. Through disposing the metamaterial panel which has the deflection function on the propagation direction of the antenna unit's electromagnetic waves, the incident electromagnetic waves are deflected. With the scheme, adjustment of an electromagnetic wave radiation direction is realized without adjusting positions of the antenna, the antenna installation cost and maintenance cost are saved, and antenna performance degradation caused by changes of antenna positions is prevented. In addition, through designing different configured metamaterial panels, different deflecting angles are obtained, so the antenna is flexible in adjustment and the deflecting angles are not restricted.

Description

technical field [0001] The invention relates to the field of antennas, more specifically, to an antenna capable of adjusting the radiation direction of electromagnetic waves. Background technique [0002] With the rapid development of wireless broadband mobile communication in recent years, in order to avoid idle equipment caused by too fast system upgrades, and to better apply new technologies, 2G / 3G or 3G / 4G dual-mode wireless communication equipment has appeared Combination, such as GSM / TD-SCDMA, TD-SCDMA / LTE. Switching between different modes requires the use of different antennas, which significantly delays the installation and design of the mobile device, and significantly increases the cost. [0003] Usually, once the antenna is installed and fixed, its electromagnetic wave radiation direction is also determined. If it is necessary to change the radiation direction of the electromagnetic wave, the fixed position of the antenna is usually adjusted by a mechanical met...
