Abstract :
We compared the performance of SI-GaAs stripline antennas with different gaps, the widths of electrodes and electrode material by experiment. Large gap antenna have high electrical to terahertz (THz) and optical to THz conversion efficiency. The dynamic range of antenna with 150 mum gap, 100 mum Au/Ge/Ni electrodes and heat sink is 6300 without purging.
