Description

technical field [0001] The invention relates to the technical field of flexible circuits, in particular to a capacitively coupled antenna-based CT detection device and an antenna manufacturing method. Background technique [0002] X-ray computed tomography imaging technology (abbreviated as "CT technology") is highly valued and widely used in the field of security inspection due to its own unique advantages. [0003] During the scanning process, the detection equipment needs to use the capacitive coupling antenna for real-time data interaction, and the capacitive coupling antenna is usually circular. [0004] However, due to the influence of technology and antenna material, the length and impedance of existing capacitively coupled antennas cannot meet actual needs, thereby reducing the transmission signal efficiency of detection equipment. Contents of the invention [0005] In view of the above analysis, the present invention aims to propose a capacitively coupled antenna...
