摘　　要：由于其载波频率更高,W波段可支持更大的带宽和更高的传输速率。因为大气损耗小,W波段信号能够进行远距离传输。进行了W波段信号的链路分析,开展了W波段毫米波通信实验的研究。由光生毫米波方法测得W波段传输系统的频率响应在10 dB变化范围内,然后采用电生毫米波系统,进行距离分别为0.8 km,1.2 km及4.4 km的W波段信号的无线传输实验。测得的接收功率分别为-19.77 dBm,-30.85 dBm及-38.61 dBm,验证了W波段信号的远距离传输特性。Due-to-high-carrier-frequency,-W-band-can-support-higher-bandwidth-and-transmission-rate.-The-signal-at-W-band-can-be-delivered-over-long-distance-because-of-small-atmospheric-loss.-Therefore,-the-transmission-link-of-W-band-signal-is-analyzed-and-the-W-band-millimeter-wave-communication-is-researched.-The-frequency-response-of-W-band-transmission-system-is-measured-by-photonic-millimeter-wave-method-and-the-measured-results-indicate-that-it-has-a-change-range-of-10-dB.-By-adopting-electric-millimeter-wave-system,-the-signal-at-W-band-is-transmitted-over-0.8-km,1.2-km-and-4.4-km-wireless-distances,-respectively.-The-received-power-is--19.77-dBm,-30.85-dBm-and--38.61-dBm-respectively.-Experiments-confirm-the-W-band-transmission-characteristics-over-long-distance.
