Summary:A 4 × 4 Ku-band high-integrated planar pattern reconfigurable array antenna is proposed. It consists of active radiating elements, and 16-way stripline feeding network. A probe-fed O-slot patch, with a compact stripline feeding line is proposed as element. Two PIN diodes are symmetrically integrated on the O-slot. By activating these diodes, each element can generate 1-bit phase resolution (0°/180°). Thus, the array can generate different patterns with linear polarization, including a single beam, two side beams, four beams, and fan beam, etc. Finally, a 1-bit 16-element pattern reconfigurable array antenna with a compact stripline feeding network are simulated. The -10 dB simulated impedance bandwidth of the single beam is 10.4%, the peak gain at 12.5 GHz is 15.3 dBi while the aperture efficiency is 67.4%. These results demonstrate that the proposed design the ability to achieve pattern reconfigurable to be a promising candidate for wireless communication systems.
