A meander line uniplanar EBG based multiband antenna using defected ground plane for WLAN and WiMAX applications

A Meander Line Uniplanar EBG based Multiband antenna using the concept of defected ground plane is presented, fabricated, tested and verified. The antenna operates at the WLAN (2.4 GHz and 5.2 GHz) as well as WiMAX band (3.6 GHz). The antenna is fabricated on the ROGERS RT 5880 substrate having relative permittivity as 2.2 and loss tangent 0.0009. The antenna maintains its gain and radiation patterns at the operating frequencies.
