| 摘 要： | 为分析毫米波短距离传输的链路损耗,提出基于距离的反射系数(distance-dependent reflection coefficient)法.研究不同极化模式、不同频率的毫米波在不同介质影响下的短距离传输链路损耗.60GHz毫米波在垂直极化和水平极化模式下的链路损耗研究结果表明,链路损耗随介电常数增大而增大.30~300GHz毫米波在两种极化模式下的链路损耗研究结果表明,链路损耗随频率增大而增大,相同频率下垂直极化模式链路损耗波动较小.

| Abstract: | In this paper we proposed a distance-dependent reflection coefficient algorithm to analyze the link transmission loss of millimeter-wave in short-distance environment.We studied the link loss of millimeter-wave short-distance transmission by using different polarization modes and different frequencies with different media.The results of the link loss of 60 GHz millimeter wave in both vertical polarization and horizontal polarization showed that the link loss increased when the dielectric constant of the reflection surface increased.The results of the link loss of millimeter wave in 30-300 GHz in two polarization modes showed that the link loss increased when frequency increased, and link loss fluctuated less in the vertical polarization mode at the same frequency. |

| Keywords: | millimeter wave link loss vertical polarization horizontal polarization reflection coefficient dielectric constant |
