Abstract

A compact and simple on-body semi closed textile antenna based on SIW technology is proposed in this communication. The motto of the designed antenna is to make it resonate at the ISM band frequencies. Initially, a basic SIW antenna with cavity is designed which resulted a single band at 8.2 GHz. To obtain an ISM band and make it suitable for on-body application a semi closed textile antenna based on SIW technology was designed. At 5.48 GHz a single band got resonated. This proposed antenna is simulated using felt as a substrate with a compact area of 0.25λ02 (λ0 is the lower order resonant frequency) and co-axial feed of 50 ohm is used as an excitation. A full wave simulator is used to simulate this semi closed SIW antenna. After the simulations a single band resonated at 5.48 GHz within an impedance bandwidth (S11<-10 dB) of 120 MHz and a unidirectional radiation pattern obtained at 5.48 GHz. A gain of 3.2 dBi is obtained. On observing the results, a single band is achieved at the ISM band frequencies and suitable for on- body applications. This proposed antenna is compact in size compared to the existing single band antennas. The secured single band at 5.48 GHz is responsible for implementing this designed antenna in Industrial, scientific and Medical applications.

基于衬底集成波导技术的小型体上织物天线

提出了一种基于SIW技术的结构紧凑、结构简单的体上半封闭式纺织天线。设计天线的座右铭是使其在ISM频段频率上谐振。最初，设计了一种带腔的基本SIW天线，得到了8.2 GHz的单频段。为了获得适合于车载应用的ISM频段，设计了一种基于SIW技术的半封闭式纺织天线。在5.48千兆赫时，一个频带产生了共振。该天线采用毛毡作为衬底，面积为0.25λ02 (λ0为低阶谐振频率)，同轴馈电为50欧姆作为激励。采用全波模拟器对该半封闭式SIW天线进行仿真。仿真后，在阻抗带宽(S11<-10 dB)为120 MHz的情况下，得到5.48 GHz的单频段谐振和5.48 GHz的单向辐射方向图。获得3.2 dBi增益。观察结果表明，在ISM频带频率上实现了单频带，适合于体上应用。与现有的单波段天线相比，该天线尺寸紧凑。5.48 GHz的安全单频段负责在工业，科学和医疗应用中实现这种设计的天线。
