摘要：
The center frequency of terahertz (THz) pulse radiated from photoconductive antenna is located at the low-frequency range of THz band. None of the antenna designs have been done to enhance the center frequency without decreasing antenna's dimension, which would largely decrease the radiation power. We introduce here the idea of separating antennas from the transmission lines to reduce the current distribution on them, showing superior performance for both the center frequency (similar to 90% increased) and the radiation power from the simulations of the dipole antennas.
