In this paper, we analyzed the rain attenuation, refraction, and reflection characteristics for short-range wireless communication applications in the terahertz band. Terahertz radio waves are attenuated by atmospheric components, rain, and moisture on the band. Therefore, it is necessary to utilize excellent propagation characteristics for terahertz communication. Terahertz has a very large rainfall intensity. It is preferable to use them indoors rather than outdoors. And 220 GHz frequency can minimize attenuation due to atmospheric components. When terahertz waves are used indoors, refraction, and reflection characteristics according to the type of indoor medium are required. The results of this paper are expected to be applicable to the propagation environment of terahertz communication systems in the future.
