摘要

提出了一种基于微带八木阵列的按钮形天线。该天线适用于工作频率为2.45 GHz的无线体域网络(WBAN)和远程医疗应用。给出了天线特性,如远场辐射方向图、耦合系数(由散射参数S11测量)和增益。此外,将所提天线的模拟性能与具有相似尺寸的圆形和矩形贴片按钮形天线进行了比较。采用基于有限积分技术(FIT)的CST Microwave Studio软件进行设计和仿真。该天线的增益为6.7 dB, (F/B)比为11.7 dB,具有在体和离体应用所需的半定向辐射方向图。

Wearable Yagi microstrip antenna for telemedicine applications
This paper presents a button shaped antenna based on a microstrip Yagi array. The proposed antenna is suitable for Wireless Body Area Network (WBAN) and telemedicine applications operating at 2.45 GHz. Antenna properties, such as far-field radiation patterns, coupling coefficient, measured by the scattering parameter S11, and gain are provided. Moreover, the simulated performance of the proposed antenna is compared to circular and rectangular patch button shaped antennas having similar sizes. Design and simulations are performed using CST Microwave Studio software which is based on the Finite Integration Technique (FIT). The proposed antenna achieved a gain of 6.7 dB, (F/B) ratio of 11.7 dB and a semi-directional radiation pattern required for on body and off body applications.
