Problems solved by technology
[0006] In the above two schemes, the former requires an additional mechanical device to realize the rotation of the reflective surface, thereby adjusting the direction of the directional antenna, which increases the mechanical complexity of the antenna; while the latter requires the use of multiple antennas. The direction adjustment depends on the adjustment of each antenna parameter in the antenna array, which increases the cost of the antenna, and the direction adjustment is more complicated

The invention provides a method and device for realizing a directional antenna and the directional antenna. The method comprises the steps that a first direction and / or a second direction are / is determined; the magnetic field of magnetic media is adjusted according to the first direction and / or the second direction; in response to adjustment of the magnetic field of the magnetic media, diamagnetic objects are redistributed in a container so as to enable the antenna to be capable of receiving or sending electromagnetic waves in the first direction and shielding the electromagnetic waves in the second direction. By the adoption of the method and device for realizing the directional antenna, distribution of the diamagnetic objects is adjusted according to changes of the magnetic field, and therefore directional electromagnetic wave transmission is realized. The mechanical complexity of the antenna is reduced, antenna arrays do not need to be adopted, the cost of the directional antenna is reduced accordingly, and direction adjustment is also simplified.
Description
technical field [0001] The present application relates to the technical field of communications, and in particular to a method and device for realizing a directional antenna and a directional antenna. Background technique [0002] Antenna is a device capable of radiating or receiving electromagnetic waves from space, and is widely used in radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, astronomy and other fields. [0003] According to the nature of work, antennas can be divided into transmitting antennas and receiving antennas; according to the working wavelength, antennas can be divided into ultra-long-wave antennas, long-wave antennas, medium-wave antennas, short-wave antennas, ultra-short-wave antennas, microwave antennas, etc.; and according to Directionality , antennas can be divided into omnidirectional antennas and directional antennas. [0004] A directional antenna refers to an antenna that radiates and ...
