摘要: An ultra wideband printed monopole antenna with dual band circular polarization for wireless application is presented. The dimensions are 30 × 1.6 mm3. proposed able to cover frequency range between 2.65 GHz and 11GHz impedance bandwidth around 122%. With the use of I-shape slit in radiation element T-slot ground plane, excited. In addition, rectangular added enhance impedance- Axial Ratio - bandwidth. Furthermore, right hand at 3.1 left 7GHz obtained. Also, 3-dB axial ratio bandwidths about 242 246 MHZ lower upper without 356 546 slit, respectively.
