Directivity/Beam control antennas are an interesting solution for wireless communication and radar application. To achieve a reconfigurable radiation pattern, active printed arrays are well suited thanks to an easy interconnection between printed technology and active devices. But a low performance is often obtained because of microstripline losses and coupling between elements. Moreover, in such frequency range, phase shifters and amplifiers are scarce and expensive. As an alternative to these conventional beam switching technologies, reconfigurable Electromagnetic Band-Gap (EBG) antennas can be used.
