Pattern reconfigurable antenna and antenna array

The invention provides a directional diagram reconfigurable antenna and an antenna array. In the embodiment of the invention, the radiation direction of the antenna is controlled by controlling the connection or disconnection of the two parasitic elements in the parasitic element pair, and finally the radiation direction of the reconfigurable antenna of the directional diagram is directionally adjusted; compared with the prior art that the radiation direction of the pattern reconfigurable antenna is directionally adjusted by pausing the feed of the antenna, the signal interruption during the switching of the radiation direction can be avoided; furthermore, in the embodiment, M parasitic element pairs are arranged in the main oscillator, and compared with a conventional mode that parasitic elements are distributed around the main oscillator, emission in the radiation direction deflects, more space is saved. 本申请提供了方向图可重构天线及天线阵列。本实施例中，通过控制该寄生元对中两个寄生元的连通或断开，来控制天线的辐射方向，最终实现了定向调整方向图可重构天线的辐射方向；这相比现有通过暂停对天线馈电来定向调整方向图
