The invention discloses a miniaturized phased-array antenna structure with
high density and
high heat consumption, and belongs to the technical field of phased-array antennae, the miniaturized phased-array antenna structure sequentially comprises an
antenna array plane, an
amplifier assembly, a TR
assembly, a power supply and a control
assembly from top to bottom, one end of a plurality of groups of radio-frequency connectors penetrates through the
amplifier assembly and is in plug-in connection with the TR assembly, and the other end of each group of radio-frequency connectors penetrates through the power supply and is in plug-in connection with the TR assembly; the other end of the
radio frequency connector is connected with an
antenna array plane in an inserted mode, a connector socket is arranged at the position, corresponding to the
radio frequency connector, of the TR assembly, and the connector socket is of an all-in-one structure. A first
air channel is formed between the
amplifier assembly and the TR assembly through heat dissipation fins, a second
air channel is formed between the TR assembly and the power supply and control assembly through heat dissipation fins, and a set of shared fan assembly is arranged on one side of the first
air channel and one side of the second air channel. According to the invention, the plug-in and pull-out problems of the high-density connector are solved; and meanwhile, the heat dissipation problem of a high-density and high-heat-consumption stacked structure is solved.
