Abstract(in English) | The telecommunication signal emission from balanced pair cable has a possibility to disturb the radio wave reception, when the high speed telecommunication signal is transmitted on a balanced pair cable. The radiated electromagnetic field from the cable has been analyzed to evaluate the influence. However, the analysis more than 300 MHz has not been carried out yet because the analysis method have not cleared. It is expected to analyze the radiated electromagnetic field from the cable more than 300 MHz corresponding to the recent high speed telecommunication system. In this report, we investigate the analysis method of the radiated electromagnetic field up to 1 GHz by presenting the balanced pair cable as a 4-port F-matrices. The results indicate that one twisted part of the cable should be divided into 100 F-matrices to achieve a converged solution, and balance-unbalance transformers, which are used to terminate the balanced pair cable, should be presented 4-port F-matrix. The calculation results are compared with the measured one. This shows that the calculated frequency response almost agree with the measured one and the cable unbalance can be presented by the same capacitance as the value used up to 300 MHz. |
