plasma antenna, conductivity and permittivity of cold plasma, mercury, VSWR, efficiency


Influence of mercury vapors in the frequency range 50-500 MHz on the specific conductivity (SC) of cold plasma of gas discharge by the loopback asymmetrical PA is probed. It is shown that in the injection of mercury vapors in the plasma antenna its conductivity grows. Two characteristic options of filling of the plasma antenna by mercury in number of 30 mg and 70 mg are probed. Taking into account data retrieved on specific conductivity in the frequency range computer simulation of the main electrodynamics characteristics of loopback PA VSWR and efficiency is executed. It is set that the more mercury impurity in the PA, the closer VSWR to 1 that is the advantage factor, on the other hand the increase in vapors of mercury leads to lowering of efficiency of PA on the average 25-30% that is undesirable. Comparing the results of calculation of VSWR as a result of experiment for PA is executed. It is recommended, for obtaining best values of VSWR and efficiency of PA and improving of an ecological situation near PA whenever possible to reduce the volume of entered mercury vapors to values of 30 mg and below.
