摘要： A dual mode band pass filter is constructed to be very compact and such that the coupling strength and bandwidth can be easily and widely adjusted while maintaining sufficient freedom of design. A metal film for forming a resonator is arranged on a first main surface of a dielectric body or at a certain height in the dielectric body. At least one ground electrode is arranged such that the ground electrode is opposed to the metal film via the dielectric body. The metal film is connected to input/output coupling circuits. In the region where the metal film is opposed to the ground electrode, two portions are partially provided. Each of these two portions has a relative permittivity that is different from the relative permittivity of the remaining portion, in order to couple two resonance modes.

摘要： A dual-mode band-pass filter having a greatly reduced size and a high design flexibility, includes a frame-shaped electrode pattern disposed on one surface or inside a dielectric substrate. A pair of input-output circuits are coupled to the frame-shaped electrode pattern. The plane shape and the line-width of the frame-shaped electrode pattern are configured so that two generated resonance modes are coupled to each other.

摘要： A band-pass filter functioning as a electronic chip component includes a chip having upper and lower surfaces, a pair of side surfaces, and first and second end surfaces facing each other. A resonator electrode is disposed in the chip. The band-pass filter also includes input and output electrodes extending in the vertical direction, which are coupled or connected to the resonator electrode, and a tubular first ground electrode surrounding the chip so as to enclose the resonator electrode. The input and output electrodes are disposed at end portions or inner sides of the tubular portion so as not to be electrically connected to the first ground electrode. The band-pass filter further includes two pairs of second ground electrodes which are disposed on both sides of the input electrode and/or output electrode and which are electrically connected to the first ground electrode.
