Abstract

The design and a computer model of a flexible graphene conical logarithmic spiral origami antenna are presented for data transmission in the ranges L, S, C, GPS L1 and L3. Its equivalent circuit (EC) has been developed. The adequacy of EC is confirmed by a computer experiment in which the thickness of the graphene helix was changed by 2 orders of magnitude. It is shown that the dependence of the frequencies of the antenna wave impedance maximums on the thickness of graphene is described by a universal function. In this case, the maximum frequencies remain stable up to a graphene thickness of ~250 µm.
