ABSTRACT:
A waveguide/planar line converter is provided which enables a simplified assembling operation and accurate positioning of a signal line. The waveguide/planar line converter includes a housing having a waveguide and a waveguide/planar line conversion substrate with a signal line propagating high frequency signals formed on one main surface side and a ground formed on the other main surface side, wherein one end portion of the signal line of the waveguide/planar line conversion substrate is located in such a manner so as to protrude into the waveguide, and the waveguide/planar line conversion substrate is arranged on the whole top surface of the housing so as to cover the mouth of the waveguide.
