Abstract |
: |
Non-uniform transmission lines have found considerable applications in microwave circuit such as resonators, transformers, matching sections and filters. For TEM mode of propagation, the non-uniform transmission line is characterized by a non constant characteristic impedance of the line along the longitudinal direction, that is along the direction of propagation of electromagnetic waves. Because of this, non-uniform transmission lines show superior transmission responses than uniform transmission lines. But, it is quite difficult to find the exact network functions of general non-uniform transmission lines, except for some special case, such as exponential transmission ,binomial transmission lines, Non-uniform transmission lines with linear and parabolic taper belong to this category. The main objectives of the thesis are to introduce and develop some selected novel non-uniform microstrip networks such as
power combiner / divider, eight ports hybrid, coupled, branch coupler and band pass filters. MATLAB programs are developed to compute their optimum elements design and frequency responses. Advance System Design simulation program is used to manufacture those circuits. The methodology of this thesis, according to objectives, is a combination of study, analysis, design and manufacture. The approach that is followed in this thesis is to study different non-uniform taper transmission lines, their types including non-uniform taper transmission lines which include exponential, linear, parabolic and radial tapers definition of parameters. |
