Abstract:
1. 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 the dielectric strip including an upper portion and a lower portion; and a suspended line including the conductor plates and 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, such that the protruding conductor pattern is sandwiched between the upper portion and the lower portion of the dielectric strip along a major portion of the protruding conductor pattern.
