| Abstract: | In this paper the wave impedaa.ee of dielectrie image line as a function of geometry dimensions and frequency is analyzed. Both the necessity and the possihility of impedance matching are studied. An optimal matching element is put forward. Its bandwidth with VSWR1.10 can be as wide as10.5 GHz, when it is connected between two dielectrie image lines with an impedance ratio of 4.7. Its properties are obviously better than those of elassical type. |
