The invention discloses a size miniaturization method for a one-to-sixteen power divider. The one-to-sixteen power divider comprises a power divider cavity, a power divider main body, a power divider input end, power divider output ends and a substrate, wherein the main body is implemented through fifteen internally-interconnected one-to-two power dividers at four stages; each segment of 1/4-wavelength impedance transformer of each one-to-two power divider cascaded at third and fourth stages is bent for five times; 50-ohm matched output micro-strip line parts of each one-to-two power divider at each stage are folded upwards and downwards towards the input end respectively; and micro-strip lines of sixteen output ports are still on the same straight line after being folded and bent, thereby bringing convenience to installation. Compared with a conventional power divider, the one-to-sixteen power divider is smaller in size, and has a relatively good performance index. Meanwhile, an output of each branch of the one-to-sixteen power divider is kept on the same straight line, and a micro-strip line circuit structure becomes more compact, so that the power divider becomes attractive, and is more convenient to use.
