Description
Technical Field

Background
With the development of flexible electronic devices, the traditional antenna design cannot meet the application requirements of novel flexible devices. And the antenna is often bulky, of large mass, occupies a very large space and is not easy to carry.
Due to the urgent need for flexible antennas, there has been a series of advances in the research of textile antennas in recent years. The textile antenna is integrated on various textiles by using the conductive cloth, so that the antenna has flexibility, simple appearance, small volume, light weight and easy wearing on human body. However, the electrical property and the manufacturing process of the material used for the textile antenna are different from those of the traditional metal antenna, and the larger deformation cannot be realized.
In recent years, wireless systems have been reduced in size and made intelligent. On the basis of textile antennas, therefore, a series of antennas made of flexible substrates have been proposed. Conical antennas, loop antennas, dipole antennas, patch antennas and the like realized by liquid metal have high deformation capacity and also bring complexity to the manufacturing process; stretchable antennas made using carbon nanotubes as the conductive material and flexible polymer substrates are also useful. The research on the flexible antenna is not completely mature, and a novel flexible antenna suitable for the surface application of the human body needs to be further researched and designed.
