摘要

本文提出了一种工作在2.45 GHz工业、科学和医疗(ISM)频段的带矩形槽的半圆形环形天线。在该可植入天线中加入工作在0.9 GHz下ISM频段的MTM分环谐振器，可获得0.9 GHz和2.45 GHz的双频频率结果。在天线的设计中采用了一些小型化的方法，例如在天线中增加一个MTM谐振器，使用具有高介电常数的Roger 3010，使用短引脚连接贴片和接地平面，以及插槽形状。为了检查MTM的存在，渗透率通过Nicolson方法提取。利用高频结构刺激器在自由空间、单层和三层组织模型中设计和模拟了所提出的天线。还计算了带和不带MTM谐振器的天线的比吸收率值和最大输入功率。

DUAL-BAND HALF-CIRCULAR RING IMPLANTABLE ANTENNA WITH METAMATERIAL SRR FOR BIOMEDICAL APPLICATIONS

This paper presents a half-circular ring antenna with a rectangular slot that operates in the industrial, scientific, and medical (ISM) band at 2.45 GHz. A metamaterial (MTM) split-ring resonator operating in the lower ISM band at 0.9 GHz is added to the proposed implantable antenna in order to obtain a dual-band frequency result of 0.9 and 2.45 GHz. Some methods of miniaturization are used in the design of the proposed antennas, such as the addition of a MTM resonator to the antenna, the use of the Roger 3010 with its high permittivity, the shorting pin to connect the patch and the ground plane, and slot shapes. To check the presence of the MTM, the permeability is extracted by the Nicolson method. A high-frequency structure stimulator is used to design and simulate the proposed antenna in free space, one-layer, and three-layer tissue models. The specific absorption rate values and the maximum input power for the antenna with and without the MTM resonator are also calculated.
