Abstract:
1. A transmission line connecting structure comprising: a plurality of connected transmission lines, each of the transmission lines including a dielectric substrate, an electrode formed on a first side of the dielectric substrate, and a first slot having a predetermined width and formed in the electrode; wherein the electrode of a first transmission line of the plurality of connected transmission lines and the electrode of a second transmission line of the plurality of connected transmission lines are positioned at a distance from one another to form a gap therebetween; wherein a respective resonator is connected to each of the plurality of connected transmission lines so as to be able to couple with one another, one end of each respective resonator being open on a side thereof facing the gap; wherein at least one stub for suppressing leakage of a first signal in the gap is provided in at least one of the electrodes of the plurality of connected transmission lines; and wherein, when the wavelength of a second signal in odd mode which propagates the plurality of connected transmission lines is λg_odd, a length of the stub is approximately λg_odd/4, and a length between the respective resonator and the stub is smaller than λg_odd/2.
