This article presents a study on a printed Yagi-Uda antenna array with a reconfigurable radiation pattern controlled by PIN diodes (BAR63-06 and BAR64-06) for WiMAX and 5G networks. The study of the two-element antenna demonstrates its ability to explore three operating modes (M1, M2, and M3): M1 offers a narrow beam for point-to-point communications or scenarios requiring strong signal concentration in a specific direction; M2 improves gain for efficient multipoint deployments such as WiMAX networks; and M3 enables uniform signal distribution or directional scanning, such as 5G backhaul connections. Overall, the results illustrate the antenna's dynamic beam adaptation capabilities, offering essential flexibility for modern wireless communication systems requiring precise radiation control and interference management.
