Discover the perfect balance: a simple dual-band vertical dipole, AN-SOF modeling, and real-world results. Elevate your ham radio experience.
Discover the vital role of historical theoretical results alongside advanced numerical calculations in accurately approximating current distribution on linear antennas.
This article validates the results obtained from AN-SOF by replicating a panel antenna model with nine dipole radiators. The model used for validation was published by the IEC and an excerpt of the document can be accessed by following this link...
The V antenna is a traveling wave antenna where high directivity can be achieved when the length of each arm of the V is greater than the wavelength. However, the angle between the arms must be chosen so that the fields radiated by both arms constructively add in the forward direction. Several authors have investigated […]
With the utilization of enhanced techniques for impedance calculation of monopoles above radial wire ground screens, our study paves the way for improved performance in LF/MF antenna design.
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 […]
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 […]
Since there is a lot of theoretical data available for the input impedance of a linear antenna, we will compare the simulation results with those obtained theoretically. Among the theoretical results, we have chosen the King-Middleton’s because from our point of view it is the most elaborate analytical solution. It is based on an expansion […]
