Abstract :
A wideband slot antenna with both linear and circular polarization (CP) is presented in this work. By embedding an arc slot, the spiral slots antenna achieve the circular polarization. The measured impedance bandwidth of a S11<;-10 dB ranges from 1.25 to 8 GHz and covers most of the commercial wireless communication systems. The measured 3-dB axial-ratio bandwidth (ARBW) is 10.6 % with respect to 1.605 GHz.
