Abstract :
A dipole-EBG array that utilizes the beam-tilting single element is presented. This enables down-tilted beam with a high directivity toward a mobile device. The proposed antenna design is fabricated and measured. The directivity of 11.2 dB is achieved at the angle of 25° at 3.5 GHz. This is higher than 9.8 dB of the directivity for the reference case that utilizes the broadside EBG-dipole single element. The array antennas exhibit a reasonable impedance matching across the operational frequency.
