SIR double periodic CRLH loaded dipole antenna

In this paper, a new printed dipole antenna loaded with double periodic cells of composite right left handed transmission line is presented. The double periodic structure is inserted at the end of the dipole as an open circuit quarter wavelength steeped impedance resonator for additional filtering function. The proposed antenna performance is compared to a reference unloaded dipole and a loaded dipole with two symmetric cells. The proposed antennas have been validated using full wave simulation. The results confirm that the proposed antenna has dual band at (1.55 GHz & 1.9 GHz) with stopband filtering up to 5 GHz. Compared to other reference dipole, it is only single band whereas the two identical cells loaded dipole has multiband; mainly at 1.1 GHz, 1.8 GHz, 2.4 GHz & 3.6 GHz but without filtering option. The proposed antenna has a good efficiency that can be applied in wireless services.
