Abstract
A line coupling structure for coupling a dielectric waveguide to a suspended line has the dielectric waveguide including dielectric strips and two conductor plates that are approximately parallel to each other, the dielectric strips and a circuit board being sandwiched between the conductor plates. The line coupling structure also has the suspended line including the conductor plates and a conductor pattern on the circuit board. The conductor pattern is arranged in a direction that is substantially perpendicular to the dielectric strips. A protruding conductor pattern that extends in the extending direction of the dielectric strips is provided at a crossing position of the conductor pattern and the dielectric strips.
Claims18
A line coupling structure comprising:
- a dielectric waveguide including a dielectric strip and two conductor plates that are substantially in parallel with each other, the dielectric strip and a circuit board being sandwiched between the two conductor plates;
- and
- a suspended line including the conductor plates and a conductor pattern on the circuit board, the conductor pattern and the dielectric strip being arranged so as to cross each other in order to be coupled with each other;
- wherein a protruding conductor pattern that extends in the extending direction of the dielectric strip is provided at a crossing portion of the conductor pattern and the dielectric strip.
