| 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。

| Abstract: | 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. |
