Abstract

The invention discloses an antenna with a reconfigurable beam direction and an antenna array with a reconfigurable beam scanning range. The antenna comprises a body, a first elastic film, a first medium, a curvature adjustment unit and at least one antenna unit, wherein the first elastic film is pasted on the body, the first elastic film and the body encircle to form a first variable volume cavity, the first medium is filled in the first variable volume cavity, the first elastic film can be elastically deformed according to volume or stress change of the first medium, the curvature adjustment unit is used for enabling the curvature of the first elastic film to change according to the stress or volume change of the first medium, and the at least one antenna unit is pasted on the outer surface of the first elastic film and is used for receiving or sending a wireless signal. With the antenna provided by the invention, the beam direction of the antenna can be very flexibly changed in a large range; and the antenna array employing the antenna is also large in beam scanning range, and the beam scanning range also can be reconfigured at any time.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to an antenna with a reconfigurable beam direction and an antenna array with a reconfigurable beam scanning range. Background technique [0002] For a specific antenna, it can receive a beam in a certain direction in space or radiate a beam in a certain direction in space. In the prior art, there are two ways to change the direction of the beam of this particular antenna. One method is to change the geometric direction of the antenna mechanically; the other is to change the current of the antenna through a phase shifter, so as to radiate beams with different directions in space. The antenna array formed by the first method is usually called a mechanical antenna array. This antenna array changes the spatial position and angle of the antenna array through mechanical movement, thereby changing the beam scanning range. The antenna array formed by the second method is generally called...
