摘要： PROBLEM TO BE SOLVED: To provide a waveguide filter whose case subjected to an iris processing and whose cover can be standardized in case of change in frequency, bandwidth and the like and which has a convenient structure making one arbitrary parameter semi-nonadjustable. SOLUTION: With respect to the waveguide filter, the case 1 is U-shaped in cross section and extends in the direction of one axis. Its flat bottom is provided with several iris parts 1a at predetermined intervals along the axis. The cover 2 has three mounting surfaces M1-M3 which can be respectively fitted to openings in the case 1. The mounting surfaces M1-M3 are in different shapes so that the cover 2 can be fitted in response to change in frequency when the bandwidth is constant (the waveguide distance a1 of the mounting surface M1 is set for the minimum frequency mode, the waveguide distance a2 of the mounting surface M2 is set for the medium frequency mode and the waveguide distance a3 of the mounting surface M3 is set for the maximum frequency mode).

摘要： PROBLEM TO BE SOLVED: To provide a waveguide that is constituted of two half split members and can be manufactured easily. SOLUTION: This waveguide 1 is constituted by joining the two half split members 2 and 3 which are split along H or E surfaces and formed of a resin or metal. In addition, this waveguide 1 has a trapezoidal, pentagonal, or hexagonal cross section in the direction perpendicular to its lengthwise direction. The half split members 2 and 3 are formed by using a molding inner frame and a molding outer frame. For example, the second internal surface 221 of the member 2 adjoining to the first internal surface 211 of the member 2 which is formed in parallel with the H-surface of the member 2 is inclined against the first internal surface 211 at an angle of ≥90.1° and COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a waveguide filter which is superior to connectivity with a flat plane circuit and easy-to-achieve in a microwave band and a millimeter- wave band. SOLUTION: A metal shield housing 10, of which the inner space part is provided with projected walls 20-25, are pasted on a grounding conductor part 50 formed on a surface on a dielectric substrate 30, and a transmission path formed on the surface of the dielectric substrate 30 is electromagnetically coupled to the inner space part of the shield housing 10, so that it becomes possible for the waveguide filter which is superior to the connectivity with the flat plane circuit formed on the dielectric substrate 30 to be configured with ease and at low costs. The shield housing 10 can be formed integrally into a cover for shielding the whole flat plane circuit, and the whole circuit, including the waveguide filter, can be configured in a small size.

摘要： PROBLEM TO BE SOLVED: To provide a high frequency module incorporating a waveguide inexpensively with high performance. SOLUTION: Opened rectangular through holes 114 are formed in two main surfaces of a first dielectric substrate 101, conductors 103 and 104 for grounding are respectively formed on the main surfaces for respectively covering the openings of the through holes 114, and conductor layers 102 are formed on the confronted wall surfaces of the dielectric substrate 101 within the through holes 114. The waveguide is structured by a space surrounded by the conductors 103 and 104 and the conductor layer 102. This waveguide is electromagnetically coupled with an input/output line 107 on a second dielectric substrate 106 via a coupling slot 105. Since the waveguide having the continuous wall surfaces can be prepared within the dielectric substrate 101, the waveguide of a small loss can be realized, and hence the high-performance high frequency module can be realized.

摘要： PROBLEM TO BE SOLVED: To lower the resonance frequency of a dielectric filter than can be used in >=5 GHz high frequency and to make the size small. SOLUTION: This filter is made in a structure connecting rectangular parallelepiped dielectrics and forms an input-output electrode in which the periphery is surrounded by a ground electrode on one surface of the respective dielectrics. A ground conductor is also formed on the surface except the joining faces of the dielectrics and a resonator is connected on the joining faces where the dielectrics are exposed to configure the filter. Recessed parts 19 and 20 which have a conductor film on the surface are formed at positions facing the input- output electrodes on the surface that is opposite to the surface on which the input-output electrodes are formed and the dielectric filter in a desired frequency is obtained by selecting its area and depth.
