摘　　要：设计了一种应用于无线局域网的由共面波导馈电的双频单极子天线。该天线在2.45和5.5 GHz频率下谐振,其(10 dB)阻抗带宽分别为2.40～2.52 GHz和4.80～7.30 GHz,覆盖了无线局域网2.4/5.2/5.8 GHz的工作频带。另外,在工作频带内,还获得了良好的全向辐射方向图和天线增益。A design of dual-band monopole antenna fed by a coplanar waveguide(CPW) for wireless local area network (WLAN) applications is presented.The antenna has resonances at 2.45 and 5.5 GHz with(10 dB) impedance bandwidths from 2.40-2.52 GHz and from 4.80-7.30 GHz which cover the 2.4/5.2/5.8 GHz WLAN operating bands.Also,good omni-directional radiation patterns and antenna gains over the operating bands have been obtained.
