Title: Investigation of gaseous attenuation on a Ka-band propagation link in tropical region
Abstract: In this paper, gaseous attenuation along a Ka-band slant path link is investigated and analyzed for the tropical country of Singapore. The signal is chosen at a frequency of 18.9 GHz with an elevation angle 44.5°. In order to estimate the gaseous attenuation along this slant path, Recommendation ITU-R P.676-10 model is applied. Four-year gaseous attenuation is processed and analyzed. The results show that for Ka-band, the water vapor attenuation is much larger than the dry air attenuation and the total maximum gaseous attenuation can be up to 0.84 dB. The seasonal variation of gaseous attenuation is mainly due to the alteration of dry/wet and hot/cool phases. In addition, the gaseous attenuation is found to keep increasing from Year 2012 to 2015, which might be due to the global warming effect.
