Abstract

This paper presents the design of the capsuleshaped patch antenna applied on fabric substrate for WBAN applications at 2.45GHz ISM band. The antenna uses Pure Copper Polyester Taffeta Fabric as a conductive substrate for ground and radiator layers, and denim as dielectric substrate. Normally, a basic rectangular antenna has a narrow bandwidth. This paper proposes the new design combining a rectangular shape with a half circular shape at both end, called the capsuleshaped antenna. The other purpose of this research is to design the antenna that can be directly installed on cloth for a WBAN small sensor. The parameters used for the analysis rely on resonance frequency. The operation frequency can be analyzed based on the reflection coefficients; it is obtained from simulation results. The antenna prototypes have been built and measured. The impedance bandwidth of prototype antenna at 10 dB with a value of 11.95% compared with 7.34% of the simulation, centered at 2.45GHz. It was found that the antenna gain from simulation and measurement was 5.63dB and 3.53dB, respectively. Finally, the radiation pattern of capsule-shaped antenna was verified by the measurement results.

WBAN应用的纺织胶囊型贴片天线设计

提出了一种用于2.45GHz ISM频段WBAN应用的织物基板上的胶囊状贴片天线的设计。天线采用纯铜聚酯塔夫绸作为地面和辐射层的导电衬底，牛仔布作为介电衬底。通常情况下，基本矩形天线的带宽很窄。本文提出了一种将矩形天线与两端半圆天线相结合的新设计，称为胶囊形天线。本研究的另一个目的是为WBAN小型传感器设计可直接安装在布上的天线。用于分析的参数依赖于共振频率。根据反射系数分析工作频率;这是由仿真结果得出的。天线原型已经建立并测量。原型天线在10 dB时的阻抗带宽为11.95%，而仿真值为7.34%，以2.45GHz为中心。仿真和测量结果表明，天线增益分别为5.63dB和3.53dB。最后，通过测量结果验证了胶囊形天线的辐射方向图。
