Abstract

A compact high-isolation diversity and circular polarized (CP) multiple-input multiple-output (MIMO) fabric antenna for 2.4 GHz ISM band applications is presented. A metamaterial (MTM)-inspired radiating element is used for the miniaturization of the presented fabric antenna. The proposed antenna is fabricated on a denim substrate and has a dimension of 58 mm x 23 mm x 1.6 mm. The circular polarization is achieved by trimming the two diagonal corners of the radiating elements. A defected ground structure (DGS) comprising two U-slots is placed underneath each radiator to increase the bandwidth of the presented antenna. The isolation characteristics between the two antenna elements are increased by 20 dB by cutting a slit in a ground plane. The proposed CP-MIMO antenna incorporates an artificial magnetic conductor (AMC) layer to limit backward radiation towards the human body and hence enhances the gain. This antenna has been created on a denim substrate with permittivity εr =1.6 and 1.6 mm thickness. The proposed antenna offers a fractional bandwidth of 6.6 % (2.38-2.54 GHz), and an impedance bandwidth about 160 MHz. The antenna has a peak gain of 2.5 dBi without AMC and 4.5 dBi with AMC. To validate the simulation results, a prototype for the proposed antenna has been fabricated and experimentally characterized. Due to its small size, low specific absorption rate (SAR), ease of integration, and robustness, this antenna is a good option for wireless body area network (WBAN) applications.
一种用于WBAN应用的具有AMC支持的紧凑型圆极化MIMO结构天线
提出了一种适用于2.4GHz ISM频带应用的紧凑型高隔离分集圆极化(CP)多输入多输出(MIMO)结构天线。超材料(MTM)启发的辐射元件被用于所提出的织物天线的小型化。所提出的天线是在牛仔布基底上制造的,尺寸为58毫米x 23毫米x 1.6毫米。圆极化是通过修剪辐射元件的两个对角来实现的。包括两个U形槽的缺陷接地结构(DGS)被放置在每个辐射器下方,以增加所提出的天线的带宽。通过在接地平面中切割狭缝,两个天线元件之间的隔离特性增加了20dB。所提出的CP-MIMO天线结合了人工磁导体(AMC)层,以限制朝向人体的反向辐射,从而提高增益。该天线是在介电常数εr=1.6和厚度为1.6 mm的牛仔布衬底上制作的。所提出的天线提供6.6%(2.38-2.54GHz)的部分带宽和大约160MHz的阻抗带宽。天线在没有AMC的情况下具有2.5dBi的峰值增益,在有AMC的条件下具有4.5dBi的峰增益。为了验证仿真结果,已经制作了所提出的天线的原型并对其进行了实验表征。由于其体积小、比吸收率(SAR)低、易于集成和鲁棒性,该天线是无线体域网(WBAN)应用的良好选择。
