WebApr 8, 2024 · The radiating graphene-based resonating structure remains less efficient [17]. The non-resonating structure of graphene does not contribute to radiation hence antenna can provide high efficiency [18]. In the case of antennas with non-resonating graphene elements, dielectric or metal based resonating structures are being preferred [19, 20].
