A DUAL BAND SNG METAMATERIAL ANTENNA FOR LTE AND WLAN APPLICATIONS

In this paper, A dual band single negative (SNG) metamaterial antenna is proposed. The antenna employs a complementary split ring resonator (CSRR) etched on the ground plane for the dual band characteristics. The proposed antenna takes the advantages of infinite wavelength, smaller footprint, and reduced design complexity offered by metamaterials for dual band characteristics. The constitutive parameters of the CSRR were obtained and validated. A peak realized gain of 5.49 dB and 6.16 dB and an efficiency of 64% and 68% were obtained at 1.8 GHz and 2.4 GHz respectively. A directional E-plane and omnidirectional H-plane patterns are obtained. The antenna has potential applications for LTE (1.88-1.92 GHz) and WLAN (2.39-2.45 GHz) networks.
