Investigation of Triple Frequency Bands Using Nano-Graphene Patch Enclosed With Copper Frame Antenna Based on (SPPs) for J-Band Applications

In this paper an investigation of a compact triple-bands are introduced using nano-graphene patch enclosed with copper frame antenna based on the surface plasmon polaritons (SPPs) and surface plasmon resonance (SPR) for the J-Band (10-20) GHz military nano-applications using HFSS. The proposed nano-antenna structure has been designed using the Rogger dielectric material of dielectric constant $\varepsilon$r=10.2 and 1.27 mm thickness. The SPP waves are generated at the interface between conducting and dielectric materials resulting in slow speed of wave propagation along the interface. As a result, the antenna’s electrical length nearly increases in relation to its physical length. Hence they the electromagnetic field is enhancement, the design resonate, the proposed nano-antenna exploits this principle for size reduction and thereby used for nano-networks communications. The proposed nano-antenna introduces triple frequency at 11.5, 14.5 and 18.9 GHz with BW=0.1,0.2 and 1.6 GHz respectively. For the incident power of one watt, the accepted power is 0.99, Umax.=0.54Watt/Str., radiated power equals 0.92, RL=−22.5dB, D=3.98, G=6.82 and the radiation efficiency is 97% for nano-applications in the military J-Band.
