The line 20 and the two ground planes 2, 3 H line design requirements must be electrically connected to the lines on different planes, and conductive paths, such as vias, conductive members, etc., can be formed in the dielectric substrate. The first coupling line 10 includes a signal input section 彳彳 and a first signal coupling section 12, and further includes a signal output section 13. The signal input section 11 and the first signal coupling section 彳2 are all on the same horizontal plane, and the horn output section 13 is located at another horizontal plane and is located between the first signal coupling section and the second ground plane 3. In this embodiment, the first signal coupling section 12 and the signal output section 13 at different horizontal planes are connected by the first via hole 41.

When the different groups of line segments have different operating frequencies, the first signal coupling section 12 and the second: number coupling section 22 can be regarded as being composed of a plurality of segments. As shown in Fig. 5, the present invention has a good degree of lightness (GQUp|ing) even under different frequencies, as shown by the curve A1; wherein, this embodiment adjusts the length of the #^degree adjustment section 24, It has the best isolation at a frequency of about 2'4 GHz, as shown by curve eight.

The long and relatively long L3 curve of segment 24 indicates that the length of the isolation adjustment segment 24 is relatively new. As can be seen from the figure, when the length of the isolation adjustment section 24 is increased, there is a problem of isolation at a relatively high frequency, and vice versa when the length of the isolation adjustment section is changed to a high isolation at a higher frequency. effect.

It can be seen from the figure that this creation does not follow The change in frequency causes the insertion loss to be heavier: the change 'insertion loss remains within the acceptable range. In summary, the facet of the present creation only needs to adjust the length of the isolation by simply changing the isolation. That is, the signal isolation can be achieved at different frequencies, and the application field of the reintegrator can be increased. When the first signal coupling section and the second signal coupling section are coupled to each other inside the dielectric substrate body, the two signal coupling sections are The wiring form can be a wraparound type, so that a sufficient length of the wire can be provided inside the small-sized dielectric substrate body, and the size of the lighter 7 M409552 can be reduced to facilitate miniaturization.
