A comparison of the effect of substrate on the performance of THz antenna

THz photoconductive material is one of the intensely studied topics in the THz field. The effect of substrate thickness on the radiated THz power had been studied by various researchers. In this paper also, THz antenna performances using different substrate material are compared and discussed. It has been shown that the thinner substrate used and the higher the electron mobility of the substrate, the higher THz radiated power produced.
