ANALYSIS OF THE PROPAGATING PROPERTIES OF PULSE VOLTAGE AND CURRENT ON DIPOLE AN TENNAS BY EQUIVALENT CIRCUIT METHOD

TL;DRAbstract

The distributed static capacitance of the dipole antenna was solved by finite di fference method. The influences of the antenna configuration coefficients on the distributed capacitance were analyzed. An equivalent circuit for dipole antenna s, which can be solved in time-domain, was put forward by the distributed static capacitance and the inductance. A corresponding time-domain approach for solvin g this circuit was proposed. By these equivalent circuit and the approach, the v alues of voltage and current at any point of the antenna and at any time can be solved, no matter what pulse source is fed to the antenna. Therefore, the propag ating properties of the pulse voltage and current along the antenna can be analy zed, and the phenomena occurring in the propagating procedure can be explained.
