▎ 摘　　要

NOVELTY - The line has a signal shielding layer arranged on a conductive metal grid structure layer. The signal shielding layer is provided with graphene. The conductive metal grid structure layer is provided with a first conductive metal grid structure layer and a second conductive metal grid structure layer. The first conductive metal grid structure layer and the second conductive metal grid structure layer are provided with a first conductive metal grid structure layer and a second conductive metal grid structure layer, respectively. USE - Microwave transmission line for a radio frequency front end module(claimed). ADVANTAGE - The graphene has high conductivity. A microporous structure of graphene can absorb a leakage signal, so as to realize the leakage signal of a conductive metal grid structure layer in the conductive process for shielding and reducing a loss of a target transmission signal. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a microwave transmission line for a radio frequency front end module.
