在本文中，提出了一种用于无线电波型内窥镜的天线传感器来检测脂肪组织中的血管。天线传感器由一根发射天线和两根接收天线组成。作为天线元件，使用微带天线。使用2.5倍比例的仿真模型讨论了天线布置与血管反射波幅度之间的关系。在模拟中，证实使用所提出的天线传感器在2.5倍比例模型中可以在距离脂肪组织顶面10mm处检测到直径10mm的血管。
In this paper, an antenna sensor for a radio-wave-type endoscope to detect a blood vessel in fatty tissue is proposed. The antenna sensor consists of one transmitting antenna and two receiving antennas. As the antenna element, microstrip antennas are used. The relationships between the antenna arrangement and the magnitude of the reflected wave from the blood vessel are discussed using a 2.5-times scale simulation model. In the simulation, it is confirmed that the blood vessel of 10 mm diameter can be detected at a distance of 10 mm from the top surface of the fatty tissue in the 2.5-times scale model using the proposed antenna sensor.
