A novel reconfigurable plasma corner reflector antenna which is composed of low cost fluorescent lamps is proposed in this paper operating at 3 GHz. The radiation characeristic of plasma corner refiector antenna is also studied by JE convolution finite-difference time-domain (JEC—FDTD) method. The study result shows that the beam shape of the CRA can be changed from single-beam to dual-beam shapes and back to omnidirectional beam shape alternately within microseconds, and the radiation characeristic of antenna can rapid reconstruction.
