“…Sometimes, the AMC-backed antenna provides bandwidth broadening [ 30 ], which can also be achieved by an L-probe-fed metasurface antenna [ 31 ]. Whereas other authors propose bandwidth enlargement combining the antennas with EBG metasurfaces [ 32 ], which can also be used to suppress surface waves and isolate the antenna from the body [ 33 ], as well as for improving the front-to-back ratio (FTBR) [ 34 ]. Moreover, involvement of both EBG and AMC metasurfaces is required to obtain beam-switching functionality and reduce the backward radiation [ 35 ].…”

Three metasurfaces (MTS) are designed to be combined with a series end-fed 1 × 10 array antenna with a modified Dolph-Chebyshev distribution for imaging applications in the millimeter frequency range, 24.05–24.25 GHz. A reduction in secondary lobes and an increase in FTBR can be achieved while preserving gain, radiation efficiency, SLL and size using an MTS–array combination. Moreover, as a result of each single-layer MTS–array combination, operation bandwidth is widened, with gain and radiation efficiency enhancement. The overall devices’ size is 86.8 × 12 × 0.762 mm3. The envisioned application is collision avoidance in aid to visually impaired people at a medium-long distance.
