Abstract

PURPOSE:To miniaturize the titled dielectric filter by providing a slit between an input terminal and an output terminal of a board so as to decrease the distance between the input and output terminals physically while assuring the transmission loss between the input and output sufficiently. CONSTITUTION:The input terminal 2 and the output terminal 3 are provided projectingly to a bottom face of the board 1 made of a dielectric, a terminal 4 is provided, the output terminal 3 and the terminal 4 are connected via an electric circuit 5 to form a prescribed length of slit between the input/output terminals 2,3. Further, the filter main body 10 is mounted on the upper face of the board 1 and the filter main body 10 is provided with plural dielectric resonators 10b imbedded in the dielectric 10a and the dielectric resonator placed at both side ends is connected respectively to the input terminal 2 and the terminal 4. Thus, the propagation of an electromagnetic wave in the board is attenuated or interrupted to improve the transmission loss characteristic between the input and output terminals. Thus, while the transmission loss between the input and output terminals is assured sufficiently, the distance between the input and output terminals is reduced and the dielectric filter is miniaturized.

When microwaves are supplied to input terminal 2, electromagnetic waves are transmitted between terminal 2 and output terminal 3 via terminal 1. Slit 6 as before
As shown in curve A, for those that are not fully engrossed,
In order to ensure sufficient transmission loss between input and output, it was rarely necessary to provide sufficient distance between people and output terminals. On the other hand, in FIG. 3 of this embodiment, since the slit 6 is provided, the dielectric substrate 1 becomes discontinuous with respect to the propagation of electromagnetic waves between the person and the output terminal 2. As shown in the figure, the transmission loss is improved compared to the conventional curve A. Furthermore, in FIGS. 4(1), (2), and (3) of this embodiment, since inserts are inserted into the slits 6, the propagation of electromagnetic waves is blocked by these inserts, as shown in curve C. In addition, transmission loss is further improved. Therefore, the necessary transmission loss can be ensured even if the distance between the person and the output terminal is reduced, and the dielectric filter can thereby be made smaller.
