In this paper, a small size, planar, dual-band antenna is proposed for ISM band applications. The antenna consists of a ground plane, a rectangular patch, and a microstrip feed line of 50 Ω. The antenna patch is loaded with several slots to obtain dual resonances in the range of 902–928 MHz and 2400–2480 MHz, covering the lower and higher ISM band frequencies, respectively. The simulated and measured results are presented to validate the proposed antenna design. The specific absorption rate results show that the proposed antenna operates within the approved standard limits and can be used as a flexible antenna.

用于ISM /可穿戴应用的平面双频天线

本文提出了一种用于ISM频段应用的小尺寸平面双频天线。天线由一个接地平面，一个矩形贴片和一个50Ω的微带馈线组成。天线贴片上装有多个插槽，以获得902–928 MHz和2400–2480 MHz范围内的双谐振，分别覆盖了较低和较高的ISM频段频率。给出了仿真和测量结果，以验证所提出的天线设计。具体的吸收率结果表明，所建议的天线在批准的标准范围内运行，可以用作柔性天线。
