A pattern reconfigurable antenna system is presented. The system is composed of a cubic array excited with a switchable feed network, a microcontroller (MCU), and a mobile application (app). The cubic array has five radiating elements, and the active state of each element is controlled by the switchable feed network. Simulated results show that the array integrated with the feed network can provide five high‐directivity scanned beams, 11 unidirectional patterns with wide beamwidth, two bidirectional patterns, and one omnidirectional pattern. For promptly switching among these radiation patterns, a MCU is used to manage the DC voltages of PIN diodes in the feed network. In addition, the used MCU has a Wi‐Fi module, and it can communicate with a mobile device through wireless area local networks. Consequently, the pattern switching can be realized with remote control. Details of system designs are described. Measured results for the array and feed network are also given.

方向性可重构天线系统的设计

提出了一种模式可重构天线系统。该系统由一个可交换馈电网络，一个微控制器（MCU）和一个移动应用程序（app）激发的立方阵列组成。立方阵列具有五个辐射元件，每个元件的活动状态由可切换的馈电网络控制。仿真结果表明，与馈电网络集成的阵列可以提供5条高方向性扫描光束，11条宽光束宽度的单向图形，2条双向图形和1条全向图形。为了在这些辐射方向图之间快速切换，MCU用于管理馈电网络中PIN二极管的直流电压。此外，使用的MCU具有Wi-Fi模块，并且可以通过无线区域局域网与移动设备进行通信。最后，模式切换可以通过遥控器实现。描述了系统设计的细节。还给出了阵列和馈电网络的测量结果。
