A Wide-Angle Beam Steering Parasitic Antenna

In this paper, a parasitic antenna with wide-angle beam scanning function is proposed. The proposed antenna is of a coaxial-fed patch antenna with four parasitic patches. Each of the parasitic patch is with one switch to tune the connection with the ground plane and obtain beam switch in four different directions on the azimuthal plane. The size of the proposed antenna is 110mm×140mm×1mm and the bandwidth is 2.38-2.41GHz.
