In this letter, measured radiation patterns of a 4×4 digitally reconfigurable transmitarray are presented. It is possible to get beam steering and polarization conversion operation using the 4×4 digitally reconfigurable transmitarray. There is a total of four PIN diodes in each unit cell of the transmitarray. The polarization conversion operation is realized using the upper two PIN diodes and the beam steering operation is realized using the lower two PIN diodes. "State1" and "State2" are the

By arranging "0" and "1" on the top and bottom layer of the transmitarray, beam steering, and polarization conversion operations can be obtained digitally. This type of transmitarray is useful for radars, satellites, and other types of communications applications.
