Abstract


In microwave system the Directional couplers are the microwave components, the broader by the one kinds Usage, e.g. the the the of a power monitoring apparatus in the signal generator and the in the the receiver mixer must Applications directional coupler device. In addition, the AGC, balanced amplifier, the the phase modulator as well as reflection-total, as and as the microwave impedance that the the electric bridges measurement instrument should also application of directional coupler. From the structure point of view, coaxial line, strip line, microstrip lines, waveguide all OK constitute a directional coupler. Therefore, the the the the type of of the directional coupler is range of, vary widely. Although the at home and abroad on the the the of the research time of of the directional coupler a long time, a wide multi-, the scope of is-Canton, in in particular yes right the rectangle waveguide to directional the coupler of the research it is a considerable mature to can be said that, However For the the ridge waveguide of the research there has been less seen in is reported. Therefore However, for to the having a the same cross-sectional Footprint ridges waveguide and rectangular waveguide, ridge waveguide are indicated by the having a wider a single - mode working bandwidth to, thus using ridge Waveguide in constituting the directional coupler than rectangular the waveguide directional coupler to having a the a wider bandwidth. Therefore directional pair of ridges waveguide the coupler to carried out the the research of the a comprehensive and systematic, not only has a the important the value of the the reality of applications, but also has a of the a certain degree of the theoretical significance. In this thesis, it combines the the existing literature directional coupler pair of ridges waveguide from the theoretical analysis, numerical calculation, The software analog aspects of carried out a a system in-depth of the research. First studied the the relatively simple the single-hole coupling situation, and apertures provided in will the a different location of the ridge Waveguide in conducted a studied. Included on this on the basis, right the the porous array coupling also carried out research and analysis. In the apertures spacing-the case of equal under, among pairs of eyelets aperture in accordance with the etc. aperture distribution, binomial distribution, the Chebyshev distribution Is this to several categories processing method \u0026 conducted to the. Related design scheme For the calculation contrast. Focus discussed the the the ridge Waveguide in of the directional coupler bandwidth in the various circumstances. Through the the on the the analysis of of the different the program compare, the the progressive realization of the design of the the most optimize the of, so as to achieve the the The purpose of of broaden the the work of bandwidth, and make it in the the has a a have more broadly applications the value of in the on the engineering practice. The of the the main research of the work of of the of this dissertation are as follows: the 1. The system derivation of and perfected the ridge waveguide directional the the of the theory the basis of of the coupler, is given a the the calculation formula of the coupled hole in the the the ridge waveguide directional coupler of the related to size as well as electromagnetic ginseng the amount of when the the a different location, in order to ridge waveguide directional the research of the coupler to provide a design theory, The a a large number of of the research the results of provides a theoretical reference basis for-oriented the research of the of the field of and related the field of. 2. On the the the small holes coupling carried out theoretical analysis and numerical calculation, and in the is carried out in the the HFSS analog, will be numerical calculation the the results of carried out contrast of the the results of with the HFSS analog, thereby confirmed the the theoretical analysis of as well as the the correctness of of the the numerical calculation of the the. 3. In the the the porous array coupling, analysis the the aperture adopt and, etc. pore size distribution, binomial distribution as well as the Chebyshev distribution pairs the expansion of which are the responsibility of the directional coupler bandwidth the impact of, come to a series of of practical conclusions. 4. Quantitative research a of the structure size of the directional coupler of its the the the impact of of the the amount of of Characteristics Parameters. 5. The use of the the Matlab language the preparation of a the auxiliary design procedures of the ridge waveguide directional coupler of the as well as the emulation program.
