Dipole Gain and Radiation Resistance
In absence of power losses, the power radiated by any antenna must be equal to its input power. In other words, the radiation resistance of a lossless antenna must match its input resistance. When comparing these two resistances we have another validation check of a numerical method. Fig. 1 shows the input resistance of a […]
Convergence of the Dipole Input Impedance
One of the validation checks consists of incrementing the number of segments as the antenna length, radius and source gap remain constant. In this way, the input impedance should converge to an asymptotic value as the number of segments increases. Fig. 1 shows the input impedance of a center-fed dipole antenna as a function of […]
