Abstract (in Japanese) (See Japanese page) 
(in English) A novel methodology is proposed for the design of ultra-wideband filters by the combination of the transmission-line-theory-based frequency-mapping-technique to a recently-proposed Chebyshev-filter-based synthesis technique. Firstly, the frequency-mapping-technique is mathematically formulated and applied to the basic distributed transmission lines elements –– short-circuited shunt stubs, open-circuited series stubs and unit elements. Then, the detailed procedure of the filter synthesis is described and demonstrated by designing an example filter with an FBW of 67%. For confirmation, a circuit simulator is used to model the synthesized filter in microstrip line. Then the filter is optimized by an EM simulator, practically fabricated and then characterized by network analyzer. The measurement results are compared with the simulation ones and the theoretical ones. Very good agreements are found and the correctness and effectiveness of the proposed technique are validated accordingly.
