A novel dual-band orthogonally-polarized MEMS reconfigurable slotted-Lozenge patch is introduced here. The dual-band performance of the lozenge patch (12 and 14 GHz) is due to different diagonal length. A cross slot is etched in the middle of patch to control the phase swing in each frequency and polarization. The effective slot length is controlled by MEMS capacitors with capacitance ratio of 1.5 resulting in phase swing of 345°. The reflect-array composed of this cell element would be able to radiate two independent beams at different frequencies and polarizations.
