This paper presents the implementation of a phased antenna array with Universal Software Radio Peripheral (USRP). The antenna elements of the array are driven by individual USRP platforms. Hence, the synchronization and calibration of different platforms are required in phase and amplitude. Calibration issues are discussed including limitations of calibrating USRPs which use WBX radio card. Planar four-element linear antenna array was used in the measurements. The prototype antenna array driven by USRPs was measured in an anechoic chamber and results show that it can create directional radiation pattern in the receiver and transmitter directions. Results show also that radiation pattern can be steered in the desired direction, by changing the excitation phase of different antenna ports.
