本文在室内住宅环境下进行了2.4 GHz离体无线信道测量，以确定不同的优值，评估了腕式贴片和PCB单极子天线在不同场景下的性能，如手腕朝向、身体旋转和露台住宅的不同房间。特别在令人关切的地区对功绩数字进行检验。结果表明，单极子天线在大多数情况下表现较好，但在深衰减和表面波扇区，贴片天线表现较好。必须提到的是，本文的主题基本上是确定一种方法，以确定在确定的关注区域中运行的任何天线的性能矩阵。最后，提出了一种新的信道增益划分方法和基于测量的窄带系统信道模型。不同扇区信道模型的多样性表明，将它们用于系统设计或射频传播分析并不是正确的方法。
This paper presents an off-body wireless channel measurement campaign at 2.4 GHz in an indoor residential environment to identify different figures of merit, which evaluates the performance of wrist - mounted Patch and PCB Monopole antennas under different scenarios, such as wrist orientations, body rotations and different rooms of a terrace house. The figures of merit are tested particularly in regions of concern. It is observed that Monopole antenna performs better in majority of the cases, however for regions of deep fades and surface wave sectors, the Patch Antenna performs better. It is imperative to mention that the theme of the paper is basically the determination of a methodology to identify performance matrices for any antenna operating in identified regions of concern. Finally, a new approach for channel gain sectorization and measurement-based channel models for narrow band systems areprovided for different rooms of a terrace House. The multiplicity of Channel Models for different sectors indicate that using them for system design or RF propagation analysis is not a right approach.
