Abstract: A new nanomaterial has the novel electrical bistable effects. This organic thin film is applied to excite the tapered slot antennas9and the nanomaterial makes the operation of the antennas more security and save the energy, which is applied in the micrometer and millimeter measurements. It is the first time to utilize the nanomaterial in the antennas structure. The finite difference time domain ( FDTD) was used in this paper to analyze the important performances of the tapered slot antennas ( TSA) , which applied the novel nanomaterial as the feeding material. The measured results are in good agreement with the calculation ones, which verifies the validity of the calculating program.
