Recent Advances in Flexible RF MEMS

“…At present, some progress has been made in the research of various functional flexible RF MEMS, mainly in flexible RF MEMS switches [ 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 ], phase shifters [ 76 , 77 , 78 ], reconfigurable antennas [ 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 ] and phased array antennas [ 87 , 88 , 89 , 90 ] based on them, in MEMS resonators [ 91 , 92 , 93 , 94 , …”

“…There are also some flexible reconfigurable antennas based on MEMS switches that are applied to various conformal application scenarios, such as reconfigurable and conformal patch antennas [ 82 ], reconfigurable and conformal patch antennas for body wireless communications [ 84 ], reconfigurable antennas based on RF switches in satellite communications [ 85 ], and reconfigurable antennas on flexible substrates for X-band [ 86 ], flexible lightweight multi-layer 16 × 16 antenna arrays [ 89 ]. However, these reconfigurable conformal antennas are not completely flexible systems, in which the MEMS switch is integrated with a rigid substrate; however, thanks to the small size of the switch, it has little impact on the flexible application of the entire antenna array.…”
