The proposed design can control the electromagnetic radiation pattern emitted by an antenna array in real time with high reliability levels. The FPGA is a Commercial of the Shelf (COTS) device based on the Anti fuse technology. The design is optimized to reduce the area overhead allowing the control of multiple antennas by means of a single FPGA. The Fault Tolerance and high reliability achieved with the design is shown by means of a new test methodology
