Power divider and method for making it

A power divider and a method for making it. The power divider includes a bottom metal layer, a first dielectric layer, an input line layer, an intermediate dielectric layer, an output line layer, a second dielectric layer, and a top metal layer provided in sequence. The bottom metal layer is provided with a first shield layer and an input port feeder. The first input ribbon line of the input line layer is connected to the input port feeder. A second input ribbon line of the input line layer is connected to the first shield layer. The top metal layer is provided with a second shield layer, a first output port feed line, and a second output port feed line. The first output feeder of the output line layer is connected to the first output port feeder. The second output feeder of the output line layer is connected to the second output port feeder. The folded segment formed by the first output ribbon line and the second output ribbon line is coupled to the folded segment formed by the first input ribbon line and th
