    For the first time, a 28 GHz additively manufactured multilayer flexible transmitarray (TA) system is introduced, utilizing inkjet printing on thin, flexible Polyethylene Terephthalate (PET) substrates.The 5.4 x 5.4 cm TA achieves ±28° 3 dB angular coverage in two axes, a solid angular coverage of 0.45 sr, and a peak gain of 15.3 dBi, all within a compact 2.6 cm thickness. Flexibility tests under varying bend radii demonstrate robust performance for conformal applications. This scalable, low-cost design sets the stage for large-area, inkjet printed flexible RF/mmWave modules. By leveraging additive manufacturing, this lightweight, ultra-low form factor TA system represents a crucial innovation in integration of TAs with space-based 5G communication architectures.
