该温度发送器主要由三部分组成:一根收发天线、一根柔性同轴电缆与一只微波空腔谐振器。空腔谐振器内充填了一种介电常数很高的陶瓷材料,其谐振频率的温度系数很大。这样空腔谐振器就成了一个温度敏感元件,可以将它植入或放在动物体内深部需要观测的器官附近。小型双极天线可植入动物皮下。天线与空腔谐振器之间用柔性同轴电缆连接起来。实验表明,用3mm粗的敏感元件装成的样机可以分辨空气中0.1℃左右的温差。若将敏
The temperature transmitter is mainly composed of three parts: a transceiver antenna, a flexible coaxial cable and a microwave cavity resonator. Cavity resonator filled with a high dielectric constant of ceramic materials, the resonance frequency of the temperature coefficient is large. This cavity resonator becomes a temperature-sensitive element that can be implanted or placed in the animal’s body near the organ to be observed. Small bipolar antenna implantable animals subcutaneous. Antenna and cavity resonator with flexible coaxial cable connected. Experiments show that the prototype with 3mm thick sensitive components can be resolved in the air about 0.1 ℃ temperature difference. If sensitive
