Abstract
The design of new transparent and metal-free absorbers for the upcoming wireless fifth-generation (5G) technology is investigated. To this purpose, innovative absorbers made of graphene-polyethylene terephthalate (PET) laminates separated by PET spacers are proposed. The graphene-PET laminates are modelled as homogeneous single layers characterized by effective conductivities whose values are obtained by means of a new analytical procedure with the aim of optimizing the absorption performances. Reflection, transmission and absorption coefficients of designed absorbers are computed considering optimum theoretical or feasible values of effective conductivities for graphene-PET laminates in order to achieve the best absorbing performance between 24.25 GHz and 42.5 GHz, i.e. in the 5G next generation bandwidth.| File | Dimensione | Formato | |
