A dual-band bow-tie antenna with enhanced tilt angle in the azimuth plane at 2.4 and 5.5 GHz is proposed. The proposed antenna consists of bow-tie radiators with dual-impedance bandwidth operating at 2.3-2.5 and 5.2-5.8 GHz. To enhance the tilt angle in the azimuth plane, an array of H-shaped meander-line unit cells as electric resonators is designed at 2.4 and 5.5 GHz with high refractive index property. Integrating the proposed array in the off-axis of the bow-tie antenna tilts the main beam radiation in the endfire direction by +17 degrees and -20 degrees at 2.4 and 5.5 GHz, respectively. When the beam is tilted by 17 degrees, there is a gain enhancement of 2.7 dBi at 5.5 GHz compared to the unloaded case.
