Abstract: A dielectric filter includes resonator electrodes, an inter-stage coupling capacitor electrode, and an input/output coupling capacitor electrode on dielectric substrates, respectively. The resonator electrodes are electro-magnetically coupled to each other to form a tri-plate structure, are made of a metallic foil embedded in a resonator dielectric substrate. Another dielectric filter includes an upper shield electrode dielectric substrate, an inter-stage coupling capacitor dielectric substrate, a resonator dielectric substrate, and an input/output coupling capacitor dielectric substrate which are made of a composite dielectric material including a high-dielectric-constant material and a low-dielectric-constant material. The above described arrangement provides the dielectric filter with an improved Q factor of a resonator, a low loss, and a high attenuation.

Abstract: PROBLEM TO BE SOLVED: To solve the problem that a development read time is widely lengthened due to countermeasures to an unwanted radiation noise since it is difficult to predict any influence of the unwanted radiation noise on the operation of electronic equipment. SOLUTION: This design support device 100 includes: an operation environment extraction part 120 for extracting an operation environment affecting the communication of an antenna 301 from among a plurality of operation environment of the electronic component 310; and a correlation value calculation part 160 for calculating a correlation value showing the degree of an influence of an electromagnetic field to be generated by the electronic component 310 on the electronic equipment based on the intensity distribution of the electromagnetic field of the electronic component 310 and the intensity distribution of the electromagnetic field of the antenna 301. Then, the correlation value calculation part 160 calculates a correlation value showing the degree of influence of the electronic component 310 on the electronic equipment about an operation environment extracted by the operation environment extraction part 120. Thus, it is possible to shorten the processing in the correlation value calculation part 160, and to simplify the processing of the design support device 100. COPYRIGHT: (C)2010,JPO&INPIT
