Abstract :
In this paper, a broadband-matched load using the multiwalled carbon nanotubes (MWCNTs) is proposed. The MWCNT-matched load could be used to match the microstrip line impedance over a broad frequency range. The measured reflection coefficient of the MWCNT-matched load is smaller than -20 dB from 3.14 to 14.82 GHz, while the corresponding radiation efficiency in this frequency range is less than 0.4%. These results demonstrate that 99% of the microstrip line power is transmitted into and dissipated by the MWCNT-matched load over a broad frequency range. Therefore, the MWCNT-matched load does serve as a broadband-matched load.
