碩士 === 國立中央大學 === 太空科學研究所 === 89 === The increasing demand for wireless broadband service throughout the world has motivated extensive research in high frequency band usages because of the large available bandwidth, high-frequency reuse, and the reduced size of transmitting and receiving antennas and electronic components. At frequency above 10 GHz, the attenuation due to rain becomes significant. In this study, we conducted a research on K band terrestrial propagation system to measure the rain attenuation in Chungli. We also made an estimation of rain attenuation in 3 metropolises in Taiwan (Taipei, Taichung, and Kaoshung). The results show that ITU-R’s rain attenuation prediction model and Robert K. Crane’s Global model both make underestimates of the rain attenuation in Taiwan.
