ABSTRACT:
An intersect-line apparatus has two conductor plates. An HE-mode dielectric resonator and four dielectric strips to be coupled to the resonator are disposed between the two conductor plates. The adjacent four dielectric strips are spaced from each other substantially at 90 degrees. Accordingly, signals propagating in two strip lines positioned substantially at 180 degrees and signals propagating in the remaining two strip lines cross each other within the dielectric resonator without interfering with each other.
