摘要
提出了一种适用于宽带WLAN的新型双频微带贴片天线结构,即在圆形贴片上开四段对称弧形环槽,再在各槽口处向外凸出小矩形槽。该结构具有良好的双谐振特性,其中心频率分别为2.44 GHz和5.25 GHz,带宽在VSWR=2时能够全覆盖ISM双波段,并且在工作波段具有良好的增益特性,均在5 dB以上。
A novel dual-frequency microstrip patch antenna for WLAN applications is presented and demonstrated. By embedding two pairs of arc shaped slots with a narrow slot protruding at each side, dual-band operation centered at 2.4 GHz and 5.2 GHz has been obtained. The proposed antenna has good gain and its impedance bandwidths defined at VSWR = 2 can meet the requirements of dual ISM bands.
