摘要

考虑到毫米和太赫兹频率下无线室内网络链路预算的基本限制。由于小的吸收面积和随之而来的路径损耗,这些频率上的单个小天线是瓶颈。虽然LOS链路与漫射环境中的链路不同,但如果不考虑复杂性,则没有理论局限性。在可能的情况下,通过使用模拟解决方案可以降低复杂性和功耗,在本文中,我们将重点放在相位共轭方法上,特别是在反向定向阵列中。仅考虑电源解决方案,我们模仿光网络,请注意一组天线。

Overview of antenna problems and solutions for multi-Gb/s links
Fundamental limitations in link budgets for wireless indoor networks are considered for millimeter and THz frequencies. Single small antennas at those frequencies are a bottle neck due to the small absorption areas and the ensuing path loss. Although different for LOS links and links in diffuse surroundings, there are no theoretical limitations, if complexity is ignored. Complexity and power consumption may be reduced by using analog solutions where possible, and in the paper we focus on phase conjugation methods, specifically in retrodirective arrays. Considering power solutions only, mimicking optical networks, we call attention to an array of rectennas.
