Abstract

The invention discloses a directional diagram reconfigurable antenna and a communication device. The directional diagram reconfigurable antenna comprises a substrate, a dipole sub-antenna radiating unit, metal sheets and graphene sheets. The dipole sub-antenna radiating unit is installed on the surface of the substrate. The graphene sheets are installed around the dipole sub-antenna radiating unit. Each metal sheet is installed between two neighboring graphene sheets. In the directional diagram reconfigurable antenna, the chemical potential of two neighboring graphene sheets is controlled by regulating a voltage value applied to two neighboring graphene sheets, so the distribution of the internal electromagnetic field of the metal sheet between two neighboring graphene sheets is changed, thereby the direction of a radiating signal of the dipole sub-antenna radiating unit is controlled, and the directional diagram reconfiguration of the antenna is realized finally. Because the teraherzfrequency band is covered by the working frequency of the graphene, the directional diagram reconfigurable antenna is capable of realizing the signal transmission and reception of a radio frequency terminal of the teraherz frequency band communication system, and improving the communication efficiency.

Description

technical field [0001] The invention relates to the field of antennas, in particular to an antenna with a reconfigurable pattern and a communication device. Background technique [0002] With the rapid development of wireless communication technology, the characteristic parameters of the antenna are required to respond quickly according to environmental changes. From this point of view, reconfigurable antennas are a good solution. An ideal reconfigurable antenna can independently adjust antenna parameters such as operating frequency, radiation pattern, and polarization according to actual needs. But according to the current research situation, only one or two parameters can be adjusted. The pattern reconfigurable antenna can avoid noise interference, improve safety, and save energy by making the signal point to the target direction. It is a very important part in the field of reconfigurable antennas. [0003] Compared with microwave communication, terahertz communication ...
