Abstract :
The transient response and the radiation pattern of the various terahertz dipole antenna were successfully obtained using FDTD method. As a result, a design guideline was presented for the trade-off between the peak height and the 3-dB bandwidth. In addition, the effect of the electrode shape and the laser beam position on the photoconductive switch was investigated
