Design and Simulation of Graphene Based Hybrid Reconfiguration Antenna
for Tera-Hertz Applications
Abstract
The present paper has been solving the problem of getting all the three
types of reconfigurations in a single antenna without using more than
one antenna and that fulfil the requirement of multifunctional system
with better performance with the confined volume at higher frequency. At
high frequency (THz), the communication system comprise of higher
transmission data rate and the low transmitting power with reliable
wireless systems. This paper represents the design and analysis of
monolayer graphene based reconfigurable array antenna (patches are 1×4
array on polyimide substrate) at terahertz (THz) band for three
reconfiguration frequency, radiation pattern and polarization. The
results obtained show that the designed antenna resonates at frequency,
0.71 THz with 10.17 dB gain, directivity, 12.69 dB as well as with 60%
efficiency, and the reconfiguration in frequency is achieved from
frequency ranges, 0.64 THz-0.74 THz, reconfiguration in radiation
pattern is achieved 82°-115° and reconfiguration in polarization is
achieved as linear, right hand circular polarization and left hand
circular polarization using commercial software CST microwave studio.
