摘要：PROBLEM TO BE SOLVED: To provide a transmission path transformer for certainly operating on a designed frequency in a high yield rate, even if characteristics variations caused by processing variations, or the like occur. SOLUTION: A waveguide driving antenna 18 connected with a feeding line pattern 15 which consists of microstrip lines is inserted in a position separated for only the predetermined space (≈λgw/4) away from a short-circuit position of the waveguide, one end of which is short-circuited. The feeding line pattern 15 is arranged in a position deviating for a deviation amount d from the center of the long side direction (Y axis direction) of an upper substrate exposed area 13. An upper surface ground pattern 14 of a dielectric substrate 10 is formed so that one boundary part thereof along the long side of the substrate exposed area 13 is projected for a projection amount p from the fixed region of the waveguide in a hollow side of the waveguide. The projection amount p and the deviation amount p are set so that two resonance points are produced in a reflection characteristic of an MSL-WG converter, and a large operation frequency band is obtained.
