A high resolution (4-bit) anisotropic transmitarray (TA) for sub-THz applications is presented here. A simple numerical model is employed to design efficiently the TA unit-cell. A 50×50 element TA optimized at 280 GHz is designed. The antenna achieves a peak gain of 28.0 dBi with 53.7% aperture efficiency at 290 GHz. The effectiveness of the design methodology demonstrates only 0.5 dB of gain loss compared to an ideal lens used for the same scenario. I.
