摘要

提出了一种线极化和圆极化的宽带缝隙天线。螺旋槽天线通过嵌入圆弧槽实现圆极化。S11< -10 dB的测量阻抗带宽范围为1.25至8 GHz，覆盖了大多数商用无线通信系统。实测的3db轴比带宽(ARBW)相对于1.605 GHz为10.6%。

A CPW-fed circularly polarized spiral slot antenna with wideband operation

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.
