论文摘要
提出了用于无线医疗身体区域网络（WMBAN）的按钮传感器天线，可通过IEEE 802.11b/g/n标准使用。由于传感器天线与人体之间的强烈相互作用，创新的稳健系统的设计具有较小的占地面积，可以提供在体内和外体内的医疗保健应用。测量和模拟的结果非常吻合。该设计在自由空间中提供了多种全向辐射模式，其反射系数（S11）为-29.30（-30.97）dB，在下部（上）频段中。 S11分别达到-23.07（-27.07）DB和-30.76（-31.12）DB，在人体胸部和手臂上。特异性吸收率（SAR）值低于1克（1.6 W/kg）和10克组织（2.0 W/kg）的调节限制。读取范围的实验测试验证了40米的最大覆盖范围的结果。
A button sensor antenna for wireless medical body area networks (WMBAN) is presented, which works through the IEEE 802.11b/g/n standard. Due to strong interaction between the sensor antenna and the body, an innovative robust system is designed with a small footprint that can serve on- and off-body healthcare applications. The measured and simulated results are in good agreement. The design offers a wide range of omnidirectional radiation patterns in free space, with a reflection coefficient (S11) of -29.30 (-30.97) dB in the lower (upper) bands. S11 reaches up to -23.07 (-27.07) dB and -30.76 (-31.12) dB, respectively, on the human body chest and arm. The Specific Absorption Rate (SAR) values are below the regulatory limitations for both 1-gram (1.6 W/Kg) and 10-gram tissues (2.0 W/Kg). Experimental tests of the read range validate the results of a maximum coverage range of 40 meters.
