Abstract

In this study, a dumbbell-shaped metamaterial (MTM) antenna has been proposed for dual-band applications using finite difference time domain (FDTD) technique. Such a composite MTM antenna consists of dumbbell-shaped patch, microstrip and partial ground plane. The proposed antenna shows dual-band behavior having impedance bandwidths (|S₁₁| < -10 dB) of 28.5% and 8.7% at 1.72 GHz and 3 GHz respectively. It has been designed to operate at various cellular standards such as GPS, GSM1800 and WCDMA. Design and analysis have been carried out using FDTD code based on uniform meshing and convolutional perfectly matched layer (CPML) absorbing boundary conditions. Further, simulation results have been verified using HFSS, and a prototype has been fabricated to validate the results experimentally. The overall electrical size of the proposed antenna is 0.287λ_o × 0.346λ_o × 0.009λ_o. The proposed dual-band antenna offers excellent radiation characteristics with a gain of 1.2 dBi and 1.5 dBi at 1.72 GHz and 3 GHz respectively with omnidirectional radiation patterns in xz-plane.
