Unit cell for 1-bit reconfigurable transmitarray with circular polarization

The unit cell structure for a transmitarray with circular polarization is presented. The unit cell operates at 5.8 GHz. The dependence of the phase shift on the unit cell parameters is investigated. The realization of the reconfigurable unit cell providing two out-of-phase states is under consideration. The proposed unit cell can be promising for a design of the transmitarray with electronic beamsteering capability. (paper)
