摘要：

We present a linearly polarized ultrawideband design for millimeter-wave phased array antennas over 17-42 GHz. The design comprises tightly coupled dipoles, integrated with a specific feeding mechanism. The proposed antenna provides a relative bandwidth of 2.7:1 and 2.47:1 with VSWR < 2 for scanning up to 45 degrees in the E- and H-planes, respectively. Several prototypes of 8 x 4 arrays are fabricated using standard PCB technology. The measurement results of the array prototypes show a good agreement with the simulations in terms of VSWR, radiation pattern, and realized gain.
