A design of pattern reconfigurable arrays realized with mechanical mechanism is presented. The radiating element of the array is a printed dipole backed with a metallic box, and it has a broad impedance bandwidth as well as a high front‐to‐back ratio. Four of the elements are connected together by using a mounting fixture with rotatable joints. When the joints are rotated manually, the array configuration is changed, and each array configuration can generate a specific radiation pattern. For the proposed array, a prototype designed at the frequency band from 4.8 to 5.9 GHz is constructed. Measured results for the prototype operating in three typical radiation modes are exhibited, including high‐directivity radiation mode, two‐beam radiation mode, and omnidirectional radiation mode. Simulated results also validate the experiments.
