Study on the Performance of Flexible Curved Inverted-F Antenna under Compound Deformation Condition

With the application of wireless communication and smart health, wearable flexible devices gradually begin to use the internet of things to transmit human health signals from the human body to the receiver, which is often realized through short-range wireless communication, such as Bluetooth or near-field communication. In order to improve the ability to receive signals, a wearable antenna attached to the surface of the human body is needed. However, muscle movement often causes damage or deformation of traditional antenna structure. In this paper, the anti-deformation ability of the curved inverted-F antenna and the communication ability under the condition of bending and stretching are studied and analyzed. The results show that CIFA has high anti-deformation ability and can adapt to the complex loading environment of human body.
