Description of the Related Art Conventionally, in an antenna sharing device in a base station such as a car phone or a mobile phone, a plurality of frequency signals are combined by a transmitting sharing device and transmitted from one antenna through an antenna line. ing. For example, in such a transmission sharing device, TE 01
A waveguide type resonator device using a δ mode is used. FIG. 11 shows a partially cutaway perspective view of the waveguide resonator device used here. In this waveguide type resonator device 20, a cylindrical dielectric resonator 12 is fixed to a support 13 inside a shielding case 11, and the dielectric resonator 12 and an external element are coupled to each other. A resonance mode coupling loop 14 is provided for this purpose, and the resonance mode coupling loop 14 is drawn out by a connector 15.

所定の値に追いこんだ構造を実現しなければならない。In FIG. 12, the impedance on the waveguide resonator device 20 side viewed from the combining point 16 is set to an open state at frequencies other than the combining wave. That is, it is realized by setting the entire electrical angle of the waveguide resonator device 20 seen from the synthesis point 16 to a predetermined condition. However, in an actual device, the line length 1 connecting the waveguide resonator device 20 and the combining point 16 is limited by the physical size.
No. 7 is restricted, and it is necessary to realize a structure in which the electric length of the resonance mode coupling loop 14 is driven to a predetermined value.

る。In the waveguide type resonator device 20, the electrical length of the resonance mode coupling loop 14 is adjusted by changing the size and shape of the resonance mode coupling loop 14. However, since the resonance mode coupling loop 14 has a specific amount of coupling with respect to its shape and shape such as a bending angle, the size and shape of the resonance mode coupling loop 14 are changed in order to adjust the electric length. Therefore, it is very difficult to independently adjust the electrical length and the coupling amount because the coupling amount changes accordingly.

なり過ぎるなどの問題がある。It is very difficult to adjust the electrical length of the resonance mode coupling loop of the conventional structure used in the waveguide type resonator device independently of the coupling amount. Adjustment was time-consuming and time-consuming. In addition, in order to adjust the impedance seen from the combination point, if the length of the line connecting the individual resonators is arbitrarily set without limiting the electrical length of the coupling loop, the line length will be short. There are problems that the resonators cannot be spaced apart from each other, or that the line length is too long and the distance between the resonators becomes long, so that the overall size of the transmission sharing apparatus becomes too large.
