In this paper, a method to configure Software Defined Array Antenna has been presented, used to measure the S$_{i1}$ parameters, and phases from four radio frequency inputs. The system setup, the waveform generating and the signal processing received of the AD9361 integrated circuit of Analog Devices and the Xilinx Zynq-7000 SoC controller, in a computer has been realized. In mode to determine the precision of the signal phase and power for array antenna applications, a 1-to-8 power divider, and a 180 degree hybrid coupler have been characterized from 0.5 GHz to 6 GHz. Finally, some possibles array antenna synthesis systems applications, beamforming algorithms, and estimation of the signal direction of arrival have been depicted.
