▎ 摘　　要

NOVELTY - The antenna has cylindrical graphene tube at frequencies of 3.96 and 5.275 Terahertz (THz) respectively. The multi band is created by adjusts the cylinder's placement and radius is order to obtain the desired effect. The emission radiation parameters of the proposed antenna, which are compared to the characteristics of ordinary transparent patch antenna in order to evaluate its performance. The antenna has a high gain of 8 decibel (Db) both with or without cylindrical tubes. USE - Hollowed aperture pentagon model graphene slot antenna. ADVANTAGE - Antenna provides improved directivity, stronger gain, larger frequency gain, and superior radiation efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an antenna.
