Abstract: A novel wideband antenna with two reconfigurable radiating patterns is presented. The proposed antenna is made of two quasi-Yagi antennas, with their radiations directing to opposite directions, respectively. The two elements are fed with one coaxial cable from the back of the dielectric substrate. A PIN diode is embedded between the feeding line of each element and coaxial cable to regulate the radiating pattern. Besides, reflectors are set under the arms of the driver dipole to regulate the radiating direction and avoid interference with radio components. Simulated results show that the proposed antenna can work at 5.00 GHz to 5.65 GHz, the main beams of the two modes direct to ±55° respectively, and the 3dB beam-widths of main beams are all 110°. The gain within the operating bandwidth is 7.3 dB to 7.7 dB. The main beam direction of the proposed antenna can be regulated by the size of reflectors. The antenna was fabricated and measured. The measurement results are good with the simulation results. The antenna presented can be used in intelligent communication systems.
