**4.3 Summary**

As mentioned above, it has been shown that the operating band of the power divider is expanded by increasing the number of stages of the LC-ladder circuit. Setting eight stages, an ultra-wideband circuit with a relative bandwidth exceeding 100% becomes possible. The effectiveness was also shown experimentally in a prototype experiment in the VHF band. With a wideband characteristic of over 100%, it is available for public radio in Japan.
