These results are simulated by using CST MW studio for the analysis effect of power loss density and intensity electric field on the dielectric load in the capacitor copper plates. By each case, the electrical power and resonant frequency are 1000 W and 39 MHz, respectively. The parameter of the simulation can be used according topic to the concept and construction. The simulation results show the distribution and intensity electric field on the dielectric load in the capacitor copper plates of the section wrapping in Z-axis at 5 mm for comparisons in each case. In Fig.4 shows the electric field distribution results of input port power for one port is the cross section in Z-axis at 5 mm. We found that the electric field distribution is propagated on the plate witch symmetrical level and the maximum level of electric field distribution is occurred at the center of plate as 1120 V/m. At the same time, the level of electric field is very low at the edge and corner. Nevertheless, it cannot propagate all of the full area. Apart from this, four feeders are optimal for coverage the more area thorn only one feeder. Fig. 5 shows the electric field distribution simulation results of input port power for four ports are the cross section in Z-axis at 5 mm as well. The maximum level of electric field distribution is occurred at the center of input port power as 324 V/m. At the same time, the level of electric field is very low at the corner Therefore, it is appropriate for analysis in this case.
