在本文中，一个紧凑的印刷曲折折叠偶极子天线的体积为114毫米（3），适合植入在一系列不同的身体组织类型与不同的电气性能，提出了在2.36-2.4 GHz MBAN和2.4-GHz ISM频段的操作。在植入体模试验台中验证其性能，并将其与线偶极子和槽加载的双极天线进行比较，该试验台包含代表具有高和低含水量的身体组织的组织等效液体。该天线在2360-2400、2400-2483.5和2483.5-2500 MHz频带内保持其回波损耗性能，尽管具有大约一半的物理长度，但与基本线偶极子相比具有等同或更好的性能。
In this paper, a compact printed meandered folded dipole antenna with a volume of 114 mm(3) suitable for implantation in a range of different body tissue types with diverse electrical properties is presented for operation in the 2.36-2.4 GHz MBAN and 2.4-GHz ISM bands. Its performance was verified and compared against that of a wire dipole and slot loaded monopole antenna in an implant phantom testbed containing tissue equivalent liquids representing body tissues with high and low water content. The antenna was shown to maintain its return loss performance in the 2360-2400, 2400-2483.5, and 2483.5-2500 MHz frequency bands with equivalent or better performance than a fundamental wire dipole despite having approximately half the physical length.
