A simple measurement method for the balanced and unbalanced modal power ratios of a small antenna is proposed. Because the conductance corresponding to each mode can be calculated by applying the S-parameter method to the power dissipated at the antenna, the modal power ratio can be obtained by measuring only the 2-port S-parameters. In this paper, we demonstrate a simulation for the analysis of the...
In this work we propose that the dipole antenna can be fed directly through the coaxial cable, without any balun, when used with a perfect electric conductor (PEC) reflector placed at quarter wavelength distance. This configuration leads to a high impedance between the coaxial cable outer metal shield at the dipole feed point and the ground plane which restricts the current to flow on the outer metal...
This paper describes the results of calculating and measuring deviations of conducted disturbance voltages caused by differences in the arrangement of an artificial mains network (AMN) used to measure the voltage, for example, the height of the (AMN) from a horizontal reference ground plane and the connection between the AMN and the ground plane. The results indicated that the conducted disturbance...
