A Review of Design and Integration Technologies for D-Band Antennas

“…Artificial magnetic conducting (AMC) structures can be designed in the BEOL metal layers below the antenna to achieve in-phase reflection, increasing the radiation efficiency. However, the achievable fractional bandwidth of a CMOSbased AMC structure at D-band is limited to around 4%, according to a model presented in [96]. In [97], an AMC structure was designed below a dipole pair by loading the BEOL dielectric with capacitive tiles.…”
