现代以身体为中心的通信系统要求良好的链路质量。当满足这一要求时,天线性能是首要的。本文提出了一种适合于以身体为中心的通信系统中天线性能量化这一困难任务的方法。在一个案例研究中,一种平面手腕可穿戴天线通过一种不需要额外开关机制的创新技术在2.4 GHz工作频段提供辐射模式切换,并在住宅环境中与单极子和贴片天线进行基准比较。天线的性能以及随后的方向图切换技术的好处被成功地量化。整体方法既包括天线测量,也包括光线跟踪的信道模拟。结果与真实世界的测量结果进行了验证。
Modern body-centric communication systems require good link quality. Antenna performance is of primary importance when meeting this requirement. This paper contributes a method suited to the difficult task of quantifying antenna performance in a body-centric communications system. In a case study, a planar wrist wearable antenna, which provides radiation pattern switching across the 2.4 GHz operating band through an innovative technique that does not require an additional switching mechanism, is benchmarked against a monopole and a patch antenna in a residential setting. The performance of the antenna and subsequently the benefits of the pattern-switching technique are successfully quantified. The holistic method includes both antenna measurements and channel simulation with ray tracing. Results are verified against real-world measurements.
