Abstract: Earlier the propagation capability of BCNTs (bunch carbon nanotubes) made antenna was studied in terahertz frequency vicinity and its fulfilments were correlated with conventionally used thin gold film antenna. Those experiments were performed on the half-wave ribbon aerial of BCNTs and then on thin gold foil antennas which were resonated from 1THz to 50THz frequency range. To calculate its radiation efficiency they use both Moment of the moment (MOM) and potential integral equation (MPIE) technique. The numerical simulated result tells us that the radiation capability of a BNCTs of density 104 (CNTs/um) antenna has typically become smaller than the capability of gold foil antenna. We have experimented with replacing BCNT by MWCNT made antenna and studied its result on the same frequency range. After examination, we found that the interband transitions hinder big problems in MWCNT. It also hinders the propagation of guided wave and gives spoiling effect basically in the achievement of a fixed dimension MWCNT when we used it as an antenna.
