Array antenna structure applied to electromagnetic radiation interference signal detection and identification

The utility model relates to an array antenna structure applied to electromagnetic radiation interference signal detection and identification. The array antenna structure comprises a mounting plate, a receiving array element and a switching diode. The number of the receiving array elements is multiple, the receiving array elements are all fixedly arranged on the mounting plate and are of an annular structure, the number of the switching diodes corresponds to the number of the receiving array elements, and each switching diode is electrically connected with each receiving array element to form a signal transmission line. The access circuit controls opening or closing of the receiving array elements, a plurality of formed signal transmission lines are connected to the circuit in parallel, whether the unit is connected to the circuit or not is controlled by adjusting on-off of the switching diodes, and therefore the beam width of the array antenna is adjusted. 本申请涉及一种应用于电磁辐射干扰信号检测识别的阵列天线结构，包括：安装板、接收阵元和开关二极管。接收阵元
