An array antenna structure with simplified phase control and antenna product(s) thereof involve at least one metal waveguide element, at least one multilayer dielectric substrate with antenna units and low-resolution phase control units and joinable to the metal waveguide element, and at least one radio-frequency (RF) front-end module electrically connected to the metal waveguide element and the multilayer dielectric substrate to enable the antenna units to radiate and/or receive RF signals. Function amplification units of the RF front-end module are electrically connected to corresponding low-resolution phase control units and an unequal-length transmission line structure. The array antenna structure uses the low-resolution phase control units to reduce cost and circuit complexity, and produces the aperiodicity of initial phase excitation of the antenna units through the unequal-length transmission line structure.
