This paper presents, a THz wideband metamaterial absorber using combination of one circular and two hexagonal rings. The absorber is the composition of vanadium dioxide (VO2), silicon dioxide (SiO2) and gold (Au) layer. The resonators has been designed on the top layer i.e. on vanadium dioxide (VO2). The numerical analysis of the proposed THz metamaterial absorber is carried out using CST microwave studio (electromagnetic field simulation software). The numerical analysis shows, absorption exceeding 97% across a bandwidth of 1.7 THz (2.9–4.6 THz). The detailed designed procedure with necessary diagram has been presented. The parametric analysis also carried out to understand the absorptance phenomena. A table also provided to compare the proposed absorber with those already available in literature. This THz absorber is used to elucidate the restricted bandwidth problem of the internet of things backhaul networks. Proposed THz absorber can also be used in landscape, energy, biology etc.
