The invention relates to the technical field of communication equipment, and provides a
millimeter wave phased-array antenna PCB laminated structure and a preparation method thereof. The
millimeter wave
phased array antenna PCB laminated structure comprises an
array element layer, a
digital control-power supply layer, a
radio frequency power layer and a PCB bottom layer, the
array element layer comprises a
radiation patch layer, a
coupling feed layer and a reference
ground layer which are arranged in a stacked mode, the
digital control-power supply layer comprises a first
ground layer, a
digital signal wiring layer and a power supply layer which are arranged in a stacked mode, a
radio frequency power division network circuit is arranged on the
radio frequency power division layer, and the PCB bottom layer, the radio frequency
power division layer, the
digital control-power supply layer and the
array element layer are sequentially arranged in a stacked mode. And a second
ground layer is arranged between the radio frequency power layer and the PCB bottom layer. The
millimeter wave phased-array antenna PCB laminated structure provided by the invention has the advantages of small thickness, simple
assembly, high reliability and the like. Through the multi-layer superposition design, the functional modules are integrated on one PCB, space utilization is optimized, the
external connection problem in the traditional design is avoided, the
assembly process is simplified, and the production efficiency is improved.
