Abstract

A novel broadband planar rotated cross monopole antenna, which consists of a vertical patch (area A) and a rotated horizontal patch (area B), is proposed. By rotating the horizontal patch, the bandwidth of the proposed antenna can be significantly enhanced. The effect of the rotated angle of the horizontal patch on the bandwidth has been deeply studied. The measured results show that the proposed antenna with compact size of 50×50 mm² can achieve a wide impedance bandwidth (10-dB reflection coefficient) as large as 8.76 GHz (2.33-11.09 GHz) or about 130%, which is nearly two times of what the corresponding conventional cross monopole antenna was.
