摘要： PURPOSE:To increase mounting density by stacking plural tri-plate lines in the thickness direction and connecting respective inner conductors through conductors made by through-hole plating to constitute a branch line coupler in three dimensions. CONSTITUTION:In the branch line coupler consisting of a three-dimensional circuit, respective inner conductors 2a, 2b of two tri-plate lines are connected through the conductors 4c made by the through-hole plating at positions 6a, 7a separated by lambdag1/4 each other. The conductors 4c are surrounded by conductors connecting conductive patterns 5a surrounding said positions 6a, 7a and constituted equivalently to a coaxial line. The length of the equivalent coaxial line can be set up to lambdag/4 by selecting the specific inductive capacity of substrates 1a,...,1c and its impedance can be set up to a required value by selecting the size of the equivalent coaxial line, so that required characteristics is obtained.

摘要： PURPOSE:To make small the size of unit, by providing the iris with the converter for the corrugate cone horn and the circular waveguide, so that the synthesized electric field with the TE11 mode wave and TM11 mode wave having the similar electric field distribution as EH11 mode wave can be obtained. CONSTITUTION:A single or a plurality of irises 5 are provided with the conversion section of the corrugate cone horn 4 and circular waveguide 3. That is, since the iris 5 as electric discontinuous section is provided at the waveguide having greater inner diameter possible for the propagation of higher order mode waves, the higher order mode is excited at the part. Further, TM11 mode is generated as the higher order mode and the irises are provided so that synthesized electric field of TM11 mode and the waveguide mode is only Y axis component at the contact surface of the conversion section and the horn. As a result, the electric field equivalent to the EH11 mode wave can be obtained in the horn.

摘要： PURPOSE:To reduce the number of cavity resonators, and to shorten the tube axial length of the waveguide by providing two coupled apertures to two modes crossing at right angles in a cylindrical resonator and a metal board to the flank with no coupled aperture provided, in parallel to the electric field of one mode. CONSTITUTION:In cylindrical waveguide 1, metal plates 3 are provided with standing surfaces parallel, dielectric plate 4 is mounted perpendicularly to the opposite surface of plate 3, and thin and long coupled aperture 5 is provided to the tube wall in the circumferential direction. Then, cylindrical resonator 9 is fitted to plate 4 at the position forming an angle of 90 deg. around the tube axis, coupled apertures 5 and 8 are coupled with two modes crossing at right angles in the cylindrical resonator against two polarized waves crossing at right angles in the waveguide, and metal plate 10 is provided at the flank side, where coupled apertures 5 and 8 are not provided, in parallel to the electric field of one mode. It is therefore possible to reduce cavity resonators in number and to shorten the tube axial length of the waveguide while maintaining flat phase characteristics over the broad range.

摘要： PURPOSE:To correct the variation of a center frequency due to a processing error by forming a cylindrical or square hole of the prescribed depth at an end of a radio wave absorbing member and extruding a metallic screw at the bottom of said hole to form an impedance matching part. CONSTITUTION:A block-shaped radio wave absorbing member covers a part or whole of the area inside the cross section of a waveguide. While a cylindrical hole 6 having the depth set at about 1/2 wavelength and a radius (a) is formed at an end of a uniform part 3 of a terminator of the radio wave absorbing member. A screw 5 satisfying a>>d (d: screw diameter) is set at the bottom of the hole 6 so that it is protruded toward the tube axis by about 1/4 wavelength. The screw 5 and the hole 6 form a matching part 4 for terminator. Thus it is possible to correct easily the variation of a center frequency due to a processing error by controlling the length of the projected axis of the screw 5.

摘要： PURPOSE:To form an impedance converter which is small in size and less in reflecting waves, by folding a coaxial line in the impedance converter. CONSTITUTION:Coaxial lines A(1), B(2) are coaxial lines with different shape and impedance characteristics. External wall of cylindrical grooves provided at a part of an inner conductor A(3) and that of an external conductor B(6) form a folding coaxial line 11. Thus, waves of radial electric field components incident from the line A(1) propagate as the waves toward the same direction to the line B(2) via the line 11. Said folding coaxal line 11 is taken as L4 in length, about 1/4 wavelength, the characteristic impedance is suitably set, allowing to form the impedance converter less in the reflection wave with small size. Two or more foldings enable small size.

摘要： PURPOSE:To obtain a transducer of low loss by provding a wave filter consisting of a convex boss, on the end of the coaxial line of the coaxial waveguide transducer by which a signal is distributed into two. CONSTITUTION:The transducer is formed by a waffle iron type wave filter 10 consisting of a convex boss, and an internal electric conductor supporting plate 11, etc., and the internal electric conductor 8 is fixed to the supporting plate 11 provided to the end of the wave filter 10. Accordingly, the equivalent short-circuit surface to a wave which performs incidence from the coaxial line 1 of the wave filter 10 is formed on the linear waveguide 2 side. This transducer is free from electrical discontinuity and the loss becomes low, since a matching element is not used.

摘要： PURPOSE:To set optionally lead-out directions of four plate lines as input and output terminals and to increase the package density of microwave parts by constituting a multilayered dielectric substrate in three dimensions in the thickness direction. CONSTITUTION:A through hole provided to strip patterns 5 and 6 is plated to connect the pattern to a strip pattern 7 and the pattern 5 of a dielectric substrate 1a to the pattern 5 of a dielectric substrate 1d electrically through base metal 3 of each dielectric substrate. A converter constituted by using dielectric substrates as mentioned above allows the transmission mode of substrates 1b and 1c to be considered equivalently as a coaxial mode. In this case, the distance between adjacent through hole plating parts of the pattern 5 is made shorter than wavelength and the characteristic impedance of this coaxial line is easily adjusted by varying the external diameter of the through hole provided to the pattern 6 and the size of an electric equivalent short-circuit surface.
