Abstract :
A novel metaresonator inspired dual band antenna for 2.4/5.2 GHz WLAN applications is presented. Dual band operation is achieved by utilizing stacking technique on a dog bone shaped dipole antenna. Stacking excites the magnetic resonance in addition to the existing dipole resonance in the structure yielding the dual band design. The antenna has a 2:1 VSWR bandwidth of 12% for the lower dipole resonance centered around 2.47 GHz and 10.5% for the second resonance at 5.18 GHz which is wide enough to cover the 2.4 GHz and 5.2 GHz WLAN applications. The antenna is made of a low cost FR4 substrate of relative permittivity 4.4 and height 1.6 mm and has a total dimension of 38×40×3.2 mm3. Experimental and simulation studies of the antenna including the stacking height variation and resonant mechanisms are explained in detail in this communication.
