An embedded quad-band WLAN antenna for laptop computers and equivalent circuit model

An embedded antenna for WLAN applications covering the frequency bands 2.4-2.48 GHz and 4.9-5.9 GHz is described. The stamped metal forming the antenna has liquid-crystalline polymer (LCP) material insert molded around it for additional mechanical support. This antenna can be mounted at various locations around a laptop screen. An equivalent circuit model is developed to explain the antenna's electrical performance.
