Sireni vln na modifikovanych sterbinovych a koplanarnich vedenich.

Due to the growing amount of data to be transferred, we have to use higher and higher frequency bands, requiring more complex circuits, in particular the high frequency parts of receivers and transmitters. Modern circuits for the centimeter- and milimeter-wave bands are produced by means of monolithic technology. In connection with the development of microwave integrated technology, special attention is paid to planar circuits produced on dielectric substrates. The main reason why they are in so much use at present lies in their low production costs. A successful design of such microwave circuits depends on precise knowledge of the type and behaviour of the waves propagating on the planar transmission lines in wide frequency bands. This thesis analyses the wave propagation on 16 different types of modified slotlines and coplanar waveguides. These lines have broad practical applications. The propagation constant and the electric field distribution of the model propagating on these lines are calculated by three full-wave methods, which are also described in the thesis.Available from STL Prague, CZ / NTK - National Technical LibrarySIGLECZCzech Republi
