The concept of a reconfigurable 5GHz microfluidically actuated antenna with beam forming, steering and hoping in a 360° angular range, is presented in this paper. Its architecture is that of a Yagi‐Uda array. Its actuation relies on the electrically controlled vertical displacement of liquid metal slugs inside microfluidic channels without the need of any external actuator. Simulation s results along two fabricated proofs of concept investigating RF and microfluidic actuation performances are presented. This paper aims at demonstrating the technical soundness and interest of this design for applications such as autonomous sensors networks.
