Wideband Printed Dipole Antenna Array for Beam Steering

We propose a wideband printed dipole antenna array with beam steering for ISM band application in this paper. The proposed printed dipole antenna with balun feeding achieves a wide impedance bandwidth of 34.16% (2.07 GHz – 2.89GHz). The gain of single antenna element is found to be 8.34 dB at 2.4 GHz. To implement the beam steering, a three-element antenna array is proposed with single balun feeding. The simulation results show a fractional bandwidth of 49.58%. The gain in the bandwidth is observed to be 9 dB – 10.9 dB and a beam steering of −22° to +14°.
