In this paper, we present a multi‐band terahertz metamaterial composed of two hexagonal shaped metallic resonators supported by a Teflon dielectric substrate. The performance characteristics of the proposed structure are evaluated numerically using CST Microwave Studio software. The design has polarization sensitive and angle independent operational nature. The designed structure resonates at five frequencies: 0.19 THz, 0.3 THz, 0.47 THz, 0.5 THz, and 0.61 THz in transverse electric mode. The underlying concept of multi‐band resonances has been understood by obtaining the electric field.
