In this paper, a novel pattern control antenna array with scanning range of 60°and operating at 2.45 GHz is designed. The continuous change of the feed phase of unit can be realized by introducing the ferroelectric material with dielectric constant controllable into the antenna array as the substrate and adding the external direct current bias to change the dielectric constant of the ferroelectric material. The antenna array consists of four parts of feed structure, isolation structure, phase shifters and antenna array elements. They are integrated into the two metal layers on both sides of the floor. Unlike other antenna design, the antenna can change the range of -30° to 30° of the maximum antenna only by controlling the magnitude of the external DC bias voltage. In addition, a novel DC bias circuit is designed, which reduces the design complexity of antenna and improves the practical value.
