Wireless network-on-chip (WNoC), with associated on-chip antennas, has been recognised as an alternative solution to overcome the performance limitations of wired networks on chip (NoC). Recently, graphene-based WNoC (GWNoC) architecture with graphene patch antennas in terahertz band was proposed as a viable alternative which can outperform traditional WNoC in terms of bandwidth, energy consumption and a number of cores per system. In this study, a novel design of dual-band re-configurable graphene-based square patch antenna is proposed with orthogonal microstrip line structure for WNoC applications. The proposed antenna can act as wireless transceiver at dual bands of 2.15–2.2 and 2.56–2.6 THz. Its performance in terms of directivity, return loss, fractional bandwidth and beam reconfiguration at different chemical potentials has been analysed.
