Abstract

A new double-layered serpentine antenna is proposed for designing an anti-metal tag with an omnidirectional radiation pattern on metallic surfaces using the concept of electric and magnetic loop currents. The zeroth-order resonance (ZOR) structure here is made up of two closely stacked serpentine lines for providing the strong capacitive reactance and parasitic elements that are required for supporting the zeroth-order resonance. Also, the geometrical parameters of the double-layered serpentine structure can control the capacitive reactance for tuning the tag resonant frequency effectively. Due to the successful excitation of the ZOR mode, our tag antenna can generate a reasonably good omnidirectional radiation pattern with a consistent read range of 7.9 m– 8.9 m (at EIRP of 4 W) on metal in all directions in the azimuth plane. It has a uniform spatial coverage ( $>$ 8 m) in the entire azimuth plane. Additionally, the antenna’s good impedance matching allows for an excellent power transmission of $\sim 99$ %. The tag resonant frequency is found to be very stable and not affected much by any changes in the backing object and the maximum measured read range is $\sim 9$ meters in $\theta \,\,{=}\,\,\pm $ 50 o at 915 MHz. It has a footprint of 50 mm $\times50$ mm ( $0.153\lambda \times 0.153\lambda$ ) with a low profile of 3.38 mm ( $0.010\lambda$ ). Furthermore, the antenna configuration is a simple folded structure around the foam substrate, without comprising any complex structures.

用于反金属标签天线设计的具有全向辐射模式的零阶蛇形天线
本文提出了一种新型双层蛇形天线,用于利用电流和磁环流的概念设计一种在金属表面具有全向辐射模式的抗金属标签。这里的零阶谐振(ZOR)结构由两条紧密堆叠的蛇形线组成,用于提供支持零阶谐振所需的强电容电抗和寄生元件。此外,双层蛇形结构的几何参数可以控制电容电抗,从而有效调节标签谐振频率。由于成功激发了 ZOR 模式,我们的标签天线可以产生相当好的全向辐射模式,在方位面的所有方向上,对金属的读取距离稳定在 7.9 米至 8.9 米之间(EIRP 为 4 W)。它在整个方位平面内具有均匀的空间覆盖范围(8 米)。此外,天线良好的阻抗匹配使其功率传输率达到 99%。标签的谐振频率非常稳定,不会受到背衬物体任何变化的影响,在 915 MHz 频率下,最大测量读取距离为 9 米。它的占地面积为 50 毫米乘以 50 美元(0.153 美元乘以 0.153 美元),外形小巧,仅为 3.38 毫米(0.010 美元)。此外,天线结构是围绕泡沫基板的简单折叠结构,不包含任何复杂结构。
