A dual band planar antenna based on metamaterial transmission lines is presented for WLAN,WiMAX,and satellite system communication applications.This antenna is composed of an interdigital capacitor and a ground plane with triangular shaped slots on its top edges to broaden the impedance bandwidth.The measured bandwidth for l0dB retu loss is from 3.29 to 4.27GHz and 5.04 to 9.8GHz,covering the 5.2/5.8GHz WLAN,3.5/5.5 GHz WiMAX bands,and the X-band satellite communication systems at 7.4 GHz.The proposed antenna exhibits stable monopole-like radiation pattes and enough gains across the dual operating bands.
