A miniaturization dual-band metamaterial (MM) model with a unit cell of hybrid-aligned hairpin split ring resonator (SRR) is proposed in this letter. The unit cell of this MM structure is a hairpin SRR, and the proposed dual-band MM is designed for security applications of wireless local-area networks (WLAN) at 2.4 GHz and worldwide interoperability for microwave access (WiMAX) at 3.5 GHz. Furthermore, a flexible substrate is adopted to improve the flexibility and practicability of the MM. Both simulated and measured results show that the center frequencies of the dual-band MM can be allocated by properly choosing the dimension parameters of the SRR. In addition, the MM are simulated at different angles of incidence, and the results reveal that the MM can operate quite well over a range of angles of incidence. Finlly, the current distribution in the MM has also been investigated to explain the mechanism of the dual-band resonance prodnced.
