Patent attributes
A millimeter-wave antenna device and a millimeter-wave antenna array device thereof are characterized in that bump portions on coaxial cable connector bases protrude into through holes of a millimeter-wave substrate to effectuate fixation thereof and ensure that the millimeter-wave substrate is tightly coupled to the coaxial cable connector bases to not only ensure the precision of the position of a feed impedance unit of a microstrip antenna structure but also ensure that, when fixed to an antenna back panel frame, a triangular configuration is effectuated such that larger antenna spacing (i.e., 8.5˜12 mm) is achieved while meeting the functional requirement of an antenna beam scan, that is, an allowance of ±30 degrees approximately, thereby circumventing a problem, i.e., the spacing between antenna units is too small to enable an external emitting/receiving module to function.
