Correct rehabilitation exercises are very important for stroke patients with partial neurological loss. This article proposes an antenna sensor, which is based on a dipole antenna and is mainly used to sense the bending angle of the joint. The experimental measurement with a self-made elbow joint fixture shows that the bending angle can be recognized very well, indicating that this method can be used in the application of prosthetics. Finally, the elbow joints, shoulder joints, and knee joints of the human body were measured for bending, and several continuous dynamic actions were designed to verify the validity of the measured benchmark values. The measurement result of the bending angle of the elbow joint shows that the bending angle can be recognized from 0 (°) to 90 (°), and the angle recognition rate is 15 (°). The measurement results of shoulder joint bending indicate that it is possible to distinguish between flat raises and hand-raising movements. To improve the accuracy and rehabilitation efficiency, you can wear better-fitting clothes and look for reference objects for measurement. The results of knee joint bending show that the use of two sets of antenna sensors and receiving antennas with different resonance frequencies can recognize the movements of standing up and sitting, while the movements of raising the legs in place will interfere with each other and the left and right feet cannot be distinguished.
