摘要： PURPOSE:To put unnecessary resonance due to a high-order mode wave out of an in-use band by providing low-impedance parts where bosses are provided and low-impedance parts where a waveguide is reduced in height alternately. CONSTITUTION:Low-impedance parts 3 where bosses 2 are provided and low- impedance parts 5 where the waveguide 1 is reduced in height are provided alternately. Low-impedance parts 5 pass only the basic mode wave and cut off the high-order mode wave, so the generated high-order mode wave causes resonance at a frequency depending upon the length l of the low-impedance part 5 shorter than the overall length of the filter in a radio-wave propagation direction. This resonance frequency is sufficiently high, so the unnecessary resonance by the high-order mode wave is put out of the passing band.
摘要翻译：目的：通过提供设置凸起的低阻抗部件和波导管交替地降低的低阻抗部件，将由于高次模波而引起的不必要的谐振从使用频带中排出。构成：设置凸起部2的低阻抗部件3和波导管1的低高度的低阻抗部件5交替地设置。低阻抗部件5仅通过基本模式波并切断高阶模式波，因此产生的高阶模式波形会根据低于整体波长的低阻抗部分5的长度l以频率产生谐振滤波器的长度在无线电波传播方向上。该共振频率足够高，所以高阶模式波的不必要的共振被超出通带。

摘要： PURPOSE:To obtain a multiplexing characteristic with broad band by inserting an inner conductor connected to a matching end from one end having small inner diameter of a group multiplexer and using an oversize waveguide for a 90 deg. phase difference plate and a 180 deg. phase difference plate. CONSTITUTION:Two circularly polarized waves in frequency fL are multiplexed at a group multiplexer 4 as two circularly polarized waves the same as the polarized wave state on the plane of an antenna 1. The two circularly polarized waves are of the TE11 mode of the basic mode of the circular waveguide and since there exists no axial component in the electric field, the waves are not subjected to the effect of the inner conductor 19. The two circularly polarized waves in the frequency fL are converted into two linearly polarized waves orthogonal to each other by the 90 deg. phase difference plate and the 180 deg. phase difference plate 10 and extracted separately at terminals 16, 17 of a polarizer 12. Since the oversized circular waveguides are used for the phase plates 8 and 10, the broad band characteristic is obtained. Since an exclusive circuit 18 is formed with the oversized waveguide, the resonance of the TM01 due to enclosing is not oscillated and no failure takes place. This characteristic is also applied to two circularly polarized waves in frequency fH.
摘要翻译：目的：通过从连接到组合多路复用器的小内径的一端插入连接到匹配端的内部导体并使用超大波导90度来获得具有宽带的复用特性。相位差板和180度。相差板。构成：频率fL中的两个圆偏振波在组多路复用器4处被复用为与天线1的平面上的偏振波状态相同的两个圆极化。两个圆偏振波是基本模式的TE11模式的圆形波导，并且由于在电场中不存在轴向分量，波不会受到内部导体19的影响。频率fL中的两个圆极化波被转换成彼此正交的两个线性偏振波在90度相位差板和180度。相位差板10，并在偏振器12的端子16,17处单独提取。由于超大圆形波导用于相位板8和10，所以获得了宽带特性。由于专用电路18由超大波导形成，所以TM01由于封闭而产生的谐振不振荡，并且不发生故障。该特性也适用于频率fH的两个圆偏振波。

摘要： PURPOSE:To obtain excellent directive coupling over a wide band, by using the combination of two directive waveguide in T-shape as branching waveguides connecting parallel waveguides. CONSTITUTION:A main waveguide 1 having terminalsI, II and a subwaveguide 2 having terminals III, IV are placed in parallel by opposing wide planes, and connected with the branching waveguides 4, 5 having about 1/4 guide wavelength. The waveguides 4, 5 are formed by combining two square waveguides in T-shape. Waves incident from the terminalIand coupled via the waveguide 4 are electric fields in the same direction and outputted to the terminals III, IV. Waves coupled via the waveguide 5 are electric fields in the opposite direction and outputted to the terminals III, IV. Thus, the waves at the terminal III are cancelled and the coupling waves are outputted to the terminal IV only. Thus, excellent directive coupling is obtained over a wide band.

摘要： PURPOSE:To reduce the coupling between subwaveguides and to decrease the loss, by pvoviding a coupling hole in parallel with a guide axis at a location, 1/2-1/4 of guide wavelength from a tip of a conductor plate distributing power and providing a resistive plate on the same plane as the conductor plate. CONSTITUTION:The conductor plate 4 is provided vertically to an electric field of the basic mode propagating in a main waveguide 1 so as to equally divide the height of the waveguide 1 into two. The coupling hole 6 in parallel with the guide axis is provided at about 1/2-1/4 of guide wavelength from the tip of the conductor plate 4, and the resistive plate 7 is fitted to a part or all of the coupling hole 6. Thus, the electromagnetic waves of the basic mode incident to the waveguide 1 are equally divided into subwaveguides 2 and 3 without being af- fected with the coupling hole 6. The coupling between the waveguides 2 and 3 is decreased. The loss to the basic mode is decreased for the power distribution.

摘要： PURPOSE:To obtain a desired elliptic polarization rate even with a small sized aperture of an electromagnetic horn, by providing a high pass waveguide apart by a 1/4-wavelength from a coupling hole provided to a main waveguide of a branching filter, and branching and absorbing electromagnetic waves of a low frequency band. CONSTITUTION:A resonator element 12 which is series resonance state to electromagnetic waves fH of a high frequency band is fitted to a coupling hole 11 provided to a main waveguide 3, and a high pass waveguide 4 which cuts off electromagnetic waves fL in a low frequency band is provided apart by a distance, about 1/4 of the waveguide wavelength or its odd number of multiple, from the coupling hole 11. The waves of fL introduced from a square waveguide 1 to the main waveguide 3 are reflected at the waveguide 4, enter a branch waveguide 13 via the coupling hole 11 and are absorbed in an electromagnetic wave absorbing body 14. On the other hand, the waves of fH introduced to the main waveguide 3 are electrically short-circuited at the resonator element 12, reach the waveguide 4 without being affected with the coupling hole 11 and are introduced to a square waveguide 5.

摘要： PURPOSE:To reduce the weight of a high frequency filter by providing an internal conductor with a part which has a large diameter and a small coefficient of linear expansion, and fixing a dielectric to the part. CONSTITUTION:A large-diameter part 9 is made of alloy with a small coefficient of linear expansion. A dielectric 4 is provided between a small-diameter part 10 and an external conductor 2, and is fixed with an adhesive in contact with the part 9 only at the boundary between the parts 10 and 9. Therefore, the dielectric 4 and part 9 have a small difference in coefficient of linear expansion and are in close contact with relatively small area, so even the addition of a temperature cycle realizes small strain at the adhesion part, obtaining stable electric characteristics. Further, the part 9 is fitted to the external conductor 2 with a screw, which is turned to vary the length of the internal conductor 3 and the capacity of a capacitor.

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 simplify circuit constitution and to eliminate influences of imbalance in amplitude and phase to a clock-wise system and counterclockwise system by making a transfer circuit into one system each for a transmission side and reception side and by providing an amplifier of the transmission side preceding more than the transfer circuit and coupler. CONSTITUTION:As for the polarization plane of a radio wave inputted to 90 deg. phase difference board 4 from transmitting-receiving branching filter 2, one elliptically polarized wave is converted by phase difference board 4 and 180 deg. phase difference board 3 into a linearly polarized wave with an x-axial polarization plane. A y-axial output generated cross-polarization branching filter 5 is amplified 7 to obtain a carrier containing no component of ''H'' from one output terminal of branch circuit 9. The output of circuit 9 is attenuated by reception-side transfer circuits 28 and 29, phase-shifted and mixed with the x-axial output by coupler 30 to obtain another carrier containing no component of ''V''. On the other hand, since amplifiers 32 and 33 in a transmitter circuit are provided preceding more than transfer circuits 22 and 23 and coupler 19, influences of imbalance in phase and amplitude with two clockwise and counter clockwise systems can be removed.
