<P>PROBLEM TO BE SOLVED: To prevent transmission characteristics from being deteriorated, by preventing reflection of a signal or unnecessary radiation to the outside at a boundary between a microstrip line and a triplate line. <P>SOLUTION: In a transmission mode converter which converts a transmission mode at the boundary portion between the microstrip line 10 including a common signal conductor 5 and the triplate line 20, in the upper ground conductor 4 of the triplate line 20, a notched part 7 wide at a boundary side and narrow in the depth, and having an approximately V-shape is formed from the boundary to the triplate line 20. <P>COPYRIGHT: (C)2009,JPO&INPIT |
