Nanoelectronics-Based Integrate Antennas

Terahertz graphene optics

“…Recently, the fundamental resonance of plasmon excitations was observed [4] in graphene ribbons, which is completely analogous to 2D plasmons observed in low mobility 2D electron gases (2DEGs) by Tsui, Allen et al in the 1970s [20] and by one of us in high mobility 2DEGs in the 2000s [19,21]. These concepts may lead to tunable graphene based antennas [22] or even nano-antennas [23][24][25][26][27][28]. At the same time, the detailed theory of the frequency-dependent conductance of graphene, especially in the THz range, is still under development [29,30].…”

Nanofibers for RF and Beyond

“…While the measurements described in this article are capable of informing the design and development of wire interconnects that incorporate nanofiber building blocks, new measurements are still needed to enable the development of nanofiber-based wireless, chip-to-chip communications. A wide variety of nanoelectronics-based antennas with spectra spanning from RFs to optical frequencies have been proposed [34]. CNTs, in particular, have been proposed as building blocks for antennas.…”

CNT-based RFID passive gas sensor

“…Several CNT based antennas have also been developed for their attractive characteristics. In [4] a CNT nanoantenna is stated to be a usually an electrically extremely short antenna, that is considerably shorter than the free-space wavelength due to its very high inductance per unit length owing to its high kinetic energy of the electrons. In [5] the use of carbon fiber composites and CNT composites is investigated for use in RFID antennas and are regarded as low cost, low weight, easy to fabricate, in addition they possess good corrosion resistance as compared to metallic surfaces, better bandwidth and may act as a matching mechanism.…”

“…In [6] CNT is used to realize conformal antennas on polymer substrates. However in [4], [5], [6] no attempt for using CNT as a sensor was taken.…”
