This document gives a view of certain active radiating elements for reconfigurable patch arrays. In literature it could be found different possibilities to obtain feasible reconfigurable antennas, whether placing the active circuitry in the transmission lines or directly over the radiating element. In this paper, the second option is chosen and active radiating elements are analyzed, designed, simulated and prototyped. Finally, measurements of these prototypes are shown. This work is part of a more complete and ambitious project whose purpose consists of designing and prototyping reconfigurable transmit-array structures for microwave applications.
