A Novel Pattern Reconfigurable Antenna Based On Liquid Metal
A novel coaxial fed pattern reconfigurable antenna based on liquid metal is proposed in this paper. The antenna state could be switched by injecting liquid metal into different shells, so that 4 radiation states are excited: +z axis beam state, conical omnidirectional beam state and two directional beam states. In addition, the structure of the antenna is simple and does not require the assistance of other complex feeding structures or parasitic structures. Statel and state2 of the proposed antenna have an overlapped impedance bandwidth from l.81GHz to 2.34 GHz (25.5%). The peak gain of statel and state2 are 8.9dBi and 4.1dBi, respectively. And the gain of state3 and state4 are both 7.2dBi at 2GHz.
