Fluid Antenna System (traditional Chinese: 流态天线系统, pinyin: Liú tài tiānxiàn xìtǒng), also known as FAS, is a wireless communication technology that refers to any software-controllable fluidic, conductive, or dielectric structure capable of altering its shape and position to reconfigure gain, radiation pattern, polarization, operating frequency, and other characteristics..[1][2] It was first introduced by Kai-Kit Wong et al. in 2020[1][3] and is recognized as the next-generation reconfigurable antenna system.[4] The system draws inspiration from Bruce Lee's Jeet Kune Do philosophy to innovate wireless communication systems design[1][2]

In an interview, Bruce Lee described the philosophy as follows:[5][6] "Be formless, shapeless like water. Now you put water into a cup, it becomes the cup. You put water into a bottle, it becomes the bottle. You put it in a teapot, it becomes the teapot. Now water can flow, or it can crash. Be water, my friend." This philosophy is applied in wireless communications, inspiring new forms of antennas that offer new opportunities and avenues for research.[1][3]. The principle behind the Fluid Antenna System is that if an antenna can be formless or shapeless, its reconfigurability and agility will be exceptional[1]. One obvious type of reconfigurable antenna that may realize Fluid Antenna System is liquid antenna, which is sometimes used as an illustrative example to showcase the concept[7],.[8] However, contrary to intuitive interpretations, Fluid Antenna System also includes designs involving no fluidic materials[1][2][3][8].[9][10] In particular, the reconfigurable pixel antenna technology can be an appealing technology to realize Fluid Antenna, with no issue regarding delay for switching its reconfigurable state[10] The emergence of Fluid Antenna System subsequently motivates new research interest among the wireless communication community, such as Movable Antenna System,[11][12] Flexible-Position MIMO,[13] Flexible Antenna Arrays,[14] etc.
