Abstract

Section titled ā€œAbstractā€

This work reports a novel and very simplistic design of a graphene based, highly directive, high gain, multi-feed, circularly polarized, 5-element diamond shaped terahertz antenna array. A design strategy is demonstrated, aiming to enhance the performance of a single element antenna, and making its radiation pattern highly directional. Being focused on lower terahertz frequency range (0.1-10 THz), it emerges as an effective radiator for inter-chip and intra-chip wireless terahertz communication. Apart from this, some other applications of this array are in communication systems for intersatellite data transmission and reception, wireless terahertz local area network, terahertz wireless nano-sensors, etc. To achieve this target, a 5-element graphene terahertz antenna array, is simulated with resonant frequency of 6.45 THz, for symmetrical diamond shaped arrangement. Results show return loss bandwidth (āˆ’10 dB) around 0.5 THz (approx. 77 <sup xmlns:mml=ā€œhttp://www.w3.org/1998/Math/MathMLā€ xmlns:xlink=ā€œhttp://www.w3.org/1999/xlinkā€&gt;&#37;&lt;/sup> ); radiation efficiency approx. 98%; isolation between ports is maintained around -30 dB; realized gain for this 5-element array is approx. 13.5 dBi; while directivity is around 14 dBi, with circular polarization confirmed by (3dB) axial ratio response having 0.15 THz, (5 <sup xmlns:mml=ā€œhttp://www.w3.org/1998/Math/MathMLā€ xmlns:xlink=ā€œhttp://www.w3.org/1999/xlinkā€&gt;&#37;&lt;/sup> ) bandwidth.
