Antennas and Beyond!

This is a blog dedicated to exploring the fascinating world of antenna design and simulation. Whether you’re a beginner or an experienced engineer, you’ll find valuable insights into antenna modeling, theory, numerical methods, and practical examples of antenna models using AN-SOF Antenna Simulation Software.

• Linear Antenna Theory: Historical Approximations and Numerical Validation

Discover the vital role of historical theoretical results alongside advanced numerical calculations in accurately approximating current distribution on linear antennas.

• Wave Matching Coefficient: Defining the Practical Near-Far Field Boundary

We explore the concepts of absolute wave impedance and wave matching coefficient (WMC) as practical alternatives to determine a useful boundary between the near and far field regions of an antenna.

• Modeling a J-Fed 5-Element Collinear Antenna for the 2 m Band

If you’re looking for a high-performing omnidirectional antenna, consider this design. It boasts 5 collinear radiant elements that are connected by phasing coils.

• On the Modeling of Radio Masts

Radiating towers or radio masts can be modeled in AN-SOF with a high degree of detail, as shown in this figure. Since we already know the omnidirectional shape of the radiation pattern, what interests us is to calculate electric field values at ground level for a given input power.

• H-Field Option in Preferences

We see that most of the time we are interested in calculating only the E-field in antenna projects when we are talking about the near field. For this reason, we have added an option to enable or disable the automatic calculation of the H-field when we click on the “Run ALL” (F10) button.

• How to Speed Up a Simulation

There is always a trade-off between speed and accuracy. However, we often need to prioritize speed in the first simulations of an antenna model. Here are some tips to speed up the calculations. The example in this figure shows that we can run a simulation more than 3 times faster.
