This work presents 2×2 and 4×4 array topologies for millimeter-wave operation, realized in High Temperature Co-fired Ceramics (HTCC) and High Thermal Coefficient Expansion (HITCE) technologies. The arrays, operating around 60 GHz, have as their main application target the ultra-high data-rate wireless communication in LOS (line-of-sight) condition, operating in the worldwide-available 60 GHz band. Two different stacked-patch topologies have been considered, one of them including an embedded air cavity, intended for enlarging the bandwidth of the structure. Prototypes of the antennas were built and measured, pointing out the differences in the realization cost and in the performances.
