However, transmitarray antennas have narrow bandwidth due to the nar– row band limitation of the transmitarray elements and the differential spatial phase delay resulting from the different lengths from the feed to each element on the transmitarray aperture.

Next the radiation performances of the space-fed arrays are described using the array theory approach. Three different methods to calculate the direc
