The invention discloses a test device and method for researching GIS partial discharge ultrahigh frequency signal propagation characteristics. The device comprises a pulse emission source, a frequency spectrograph, at least one first ultrahigh frequency sensor, at least one propagation attenuation characteristic test structure and a data processing module. The propagation attenuation characteristic test structure comprises at least four second ultrahigh frequency sensors; the pulse emission source is connected with any one of the first ultrahigh frequency sensors; the frequency spectrograph is respectively connected with the at least four second ultrahigh frequency sensors and the pulse emission source; the pulse emission source is used for emitting a first ultrahigh-frequency electromagnetic wave signal; the second ultrahigh-frequency sensor is used for acquiring a second ultrahigh-frequency electromagnetic wave signal; the frequency spectrograph is used for measuring the insertion loss of the second ultrahi
