Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a multi-microstrip line connector for connecting a plurality of microstrip lines.

"Prior Art" Conventionally, when connecting a microstrip line formed on a printed circuit board, it was converted into a coaxial line by a coaxial connector and then connected.

The transmission mode of the strip line and the transmission mode of the coaxial line are the same TEM wave mode, but since the shapes of both lines are different, it is difficult to achieve matching at the joint portion of both lines.

Although the stripline can be realized at a low price, the coaxial connector was relatively expensive.

While the stripline is essentially an unbalanced mode, it is difficult to make a matched connection with a normal connector equivalent to a balanced 2-wire with balanced mode.
