Graphene-based tunable terahertz self-diplexing/MIMO-STAR antenna with pattern diversity
This paper presents a tunable terahertz (THz) two-port graphene patch antenna having isolation between the ports of the order of 40 dB over the whole range of tunability. This antenna could either be used in self-diplexing mode or as a multi-input–multi-output (MIMO) antenna with pattern diversity that can support simultaneous-transmit-and-receive (STAR) mode of operation with its high port-level isolation. The antenna structure through numerical analysis is optimized to provide the highest isolation and good impedance matching. A detailed analysis of the antenna modes is carried out to get insight into the impedance matching and radiation mechanism. An electrical equivalent circuit is proposed for the MIMO graphene patch antenna to get a better understanding of its operation. Furthermore, a linear regression model is introduced to help in determination of the chemical potentials of the two graphene radiators for different frequencies of MIMO operation.
