Abstract-Transmitarray antennas are being developed to significantly reduce the mass and the cost of beamforming antennas for satellite communication. A generalized methodology to design low profile transmitarray antennas made of several stacked layers with non-resonant printed phasing elements is presented. A study of the unit cell bandwidth, phase-shift range and tolerances has been conducted considering different numbers of layers. A structure with 3 metallized layers with capacitive and inductive elements enabling a phase range of nearly 360 degrees and low insertion loss is introduced. An implementation on a flexible substrate of a transmitarray with progressive phase shift operating at 19GHz is used for validation.
