Abstract

This paper investigated two kinds of design of implant antennas in ultra wide-band (UWB) low-band (3.4-4.8 GHz) for capsule endoscopes. First, two kinds of hemispherical antennas, one has a helical structure and the other has a loop structure, were designed. The hemispherical antennas match for the shape of capsule endoscopes. The reflection coefficient S11 and the directivity of the hemispherical antennas in UWB low-band were investigated in detail. Next, a simplified planar design of the hemispherical loop antenna was proposed for being easy to fabricate. The characteristic of the planar loop antenna in UWB low-band was investigated by both numerical simulation and experiment. In addition to the S11, the path loss of the fabricated planar loop antenna was also measured in a fluid phantom simulating a human body tissue, with a planar unbalance dipole antenna as the receiving antenna. The measured path loss was compared with the simulated result, and good agreement was confirmed between them.

用于胶囊内窥镜的超宽带低频段植入天线设计

研究了两种用于胶囊内窥镜的超宽带(UWB)低频段(3.4-4.8 GHz)植入天线的设计。首先，设计了两种半球形天线，一种是螺旋结构，另一种是环形结构。半球形天线与胶囊内窥镜的形状相匹配。详细研究了半球形天线在超宽带低频段的反射系数S11和指向性。其次，为了便于制作，提出了一种简化的半球形环形天线平面设计方案。通过数值模拟和实验研究了平面环形天线在超宽带低频段的特性。除了S11外，还在模拟人体组织的流体模体中，以平面不平衡偶极子天线作为接收天线，测量了制备的平面环形天线的路径损耗。将实测路径损耗与仿真结果进行了比较，两者吻合较好。
