A novel broadband rotated-patch antenna for wireless communication applications is proposed. By rotating the rectangular patches symmetrically, the bandwidth of the antenna can be significantly enhanced. Especially, the effect of the rotating angle and other geometry parameters on the bandwidth has been studied in detail. An antenna prototype is then fabricated and measured to verify the effectiveness of this design. The measured results indicate that the proposed antenna can achieve an impedance bandwidth (10dB return loss) as wide as 6.97GHz (2.29~9.26GHz) or the relative bandwidth is about 120.7%, which is nearly two times what the corresponding conventional cross monopole antenna does. Also relatively good omnidirectional radiation performance and antenna gain over the whole frequency range have been achieved.

Key words: planar antenna, broadband, omnidirectional, low profile
