While on one hand 5G and beyond 5G networks are challenged by ultra-high data rates in wideband applications like 100+ Gb/s wireless Internet access, on the other hand they are expected to support reliable low-latency Internet of Things applications with ultra-high connectivity. These conflicting challenges are addressed in a system proposal dealing with both extremes. In contrast to most recent publications, focus is on the frequency domain below 10 GHz. Toward this goal, multi-mode antenna technology is used, and different realizations, offering up to eight uncorrelated ports per radiator element, are studied. Possible baseband architectures tailored to multimode antennas are discussed, enabling different options regarding precoding and beamforming.

多模天线在 10 GHz 以下超宽带和物联网应用中的可行性

一方面，5G 及更高版本的 5G 网络受到宽带应用（如 100+ Gb/s 无线互联网接入）中超高数据速率的挑战，另一方面，它们有望支持可靠的低延迟物联网应用，具有超高连通性。这些相互矛盾的挑战在处理这两种极端情况的系统提案中得到解决。与最近的出版物相比，重点是 10 GHz 以下的频域。为了实现这一目标，我们使用了多模天线技术，并研究了不同的实现方式，每个辐射器元件提供多达八个不相关的端口。讨论了针对多模天线定制的可能基带架构，从而支持有关预编码和波束成形的不同选项。
