Background With the evolution of technology and the expansion of service, the information processing requirement is expanded, and the communication perception integration becomes one of the dominant trends of future technology and service. Future networks are expected to be a convergence of mobile communication networks, awareness networks, and power networks. In a conventional network, communication and perception exist independently, and the communication and perception integrated design can reduce the waste of wireless spectrum and hardware resources and reduce the time delay in information processing. Disclosure of Invention The invention mainly aims to provide an antenna unit and an antenna array, which aim to integrate a communication function and a signal sensing function of a communication network so as to realize the integrated setting of the sense of openness. To achieve the above object, the present invention proposes an antenna unit, wherein the antenna unit includes: a plurality of radiating elements arranged in a longitudinal first direction; at least one feeding part electrically connected with the radiating oscillator through a feeding channel respectively, and And the switching device is arranged on the feeding channel and is used for controlling the on-off between at least one radiation oscillator and the feeding part.

In the technical scheme of the application, when the antenna unit is used for communication, a plurality of radiating vibrators are communicated with the feeding part generally, so that the furthest radiating distance is obtained, and the communication quality is ensured. At this time, the beam angles of the plurality of radiation oscillators after being loaded are smaller, so that the communication requirement can be met, but when the antenna unit is used for sensing signals, the space coverage rate of the smaller beam angles in the first direction is low, although the coverage rate of the beams in the first direction can be improved by carrying out multi-channel digital scanning on the antenna unit or adding the phase shifters for analog beam scanning, the multi-channel digital scanning needs to increase the number of channels and expand the antenna array surface, the realization cost is high, and in the scheme of increasing the phase shifters for analog beam scanning, the antenna array surface does not need to be expanded, but a plurality of phase shifters need to be added, the control is complex, and the same cost is high. Therefore, in the application, the switch device is arranged on the feeding channel, the quantity of the radiation vibrators working in the antenna unit is controlled by the switch device, so that when the antenna unit is used for sensing signals, the working radiation vibrators can be reduced, the sensing distance is shortened, but a larger beam angle is obtained, the sensing coverage in the first direction is improved, the space coverage requirement of the sensing signals is met, and the scheme is simple in arrangement, low in cost and good in effect. Meanwhile, when the antenna unit is used for communication, the switch device can be controlled to enable the plurality of radiating vibrators to be communicated with the feeding part, the communication use state of the antenna unit is restored, and the communication function of the antenna unit is not affected.
