Many consider antenna modeling programs to be "overkill" for most if not all ham radio antenna experimenters needs. The first benefit you get from using a good antenna design program is a much better understanding of all the parameters and compromises that go into the design of an antenna system. To be honest, there is a cost to this type of software. Your time! You will have to invest a bit of time up front to learn But the time invested in learning how to design your own antennas will bring very appreciable returns.
Roger's version is certainly worth looking into if the above mentioned software does not meet your requirements and expectations. You can download mNEC v. On the other hand, 4NEC2 let's you subdivide your antenna into segments default! That means higher accuracy and the possibility of modeling complex antenna systems.
Want to run more than the default ! See the FAQ on the site. I have not tested it on later versions. Try it anyway! It might work. Some things still come with a price tag in this world! The antenna software packing those little extras you just can't live without is one of those things! The designing and building of antennas is a very wide subject. It has become a hobby within a hobby for many of us. Much has been written on the subject. Some of it cannot be ignored. For example It will help you understand antenna modeling and evaluate the antenna software available.
An absolute must for true antenna enthusiasts who need to get the most out of their antenna software, especially those at ease in a more technical environment. Believe it or not, there is an infopreneur online entrepreneur in many of us! Often, all you need to make it bloom is proper guidance. You can get it here. Here is one way to squeeze in a resonant meter antenna no coils where you don't have enough horizontal space for a full-length dipole. This article describes how to build a vertical dipole antenna for 20, 15 and 10 meters.
I can visualize problematic areas using the powerful graphical tools provided. Post-processing TDR function also helps me match design with lab measurements. Their software's extensive capabilities, as well as a seamless integration with Solidworks, have proven invaluable in performing numerous complex simulations.
The ability to parameterize studies, as well as to quickly and easily communicate results using the built-in template, has made EMW a powerful tool in our design process. In addition, the EMWorks technical team has been exceptionally responsive and quick to assist us with any and all issues. We greatly appreciate your software and dedication to the success of our efforts, and look forward to our continued collaboration. I used EMWorks for an undergraduate biomedical engineering project.
I am thankful that EMWorks is very well integrated with SolidWorks, which makes constructing 3D geometries straight-forward. The step-by-step tutorial of EMWorks also helped me in learning the software. Many other multiphysics software applications don't have easy-to-use tutorials. Overall, EMWorks has been helpful software for my project.
I was very impressed with one click I was able to obtain TDR results of my RF model which really gives me everything I am looking for, especially when other software like HFSS makes it such a pain to get similar results. Whether you are interested in frequency response, resonance behavior, electromagnetic interference, matching networks, filtering characteristics, attenuation, electromagnetic radiation, electromagnetic waves, electromagnetic propagation, electromagnetic compatibility issues, you will find this 3D field EM simulation tool accurate, fast, versatile, and easy-to-use.
It is an antenna software as much as it is a filter, a resonator, an EMC, an EMI, a passive component, a signal integrity, and power integrity software. Its seamless CAD integration enables you to analyze the most complex high frequency and high speed electrical and electronics devices and circuits in record time because you do not need to create a special model for the electromagnetic simulation. Intuitive and easy to use graphical user interface. It allows user to construct and simulate complex 3D models in record time.
HFWorks enables numerous analyses to obtain the best design for your application. This serves as a first step to optimize your designs. HFWorks comes with a Time Domain Analysis type that helps designers to allocate discontinuities in connectors, adapters, cable transitions and high speed interconnects. It is a very important issue for RF connectors and cables manufacturers. It offers you a coherent environment where you can simultaneously study the electrical and thermal behavior of your high frequency design right on the same model with one single finite element mesh.
Hence, in addition to the plethora of electrical and electronic design parameters, you can also obtain the temperature, temperature gradient, and heat flux of your high frequency design due to conductor and dielectric losses. Dielectric breakdown is a key limiter of power handling as it can lead to catastrophic failure. HFWorks produces safety factor maps that indicate where breakdown has occurred in the model or where it is most likely to occur for a given level or excitation power or stored energy.
Runaway thermal breakdown can also occur if any part of the design is subject to excessive heat due to RF power losses. These features save users costly and time consuming experimental setups that are often required to establish power rating and handling capabilities of their products.
Mini Atlass: is an analysis and synthesis program for computing electrical and physical parameters of different types of transmission lines.
It communicates directly with SolidWorks to create the structure. Scattering parameters or S-parameters the elements of a scattering matrix or S-matrix describe the electrical behaviours of linear electrical networks when undergoing various steady state stimuli by electrical signals. Although applicable at any frequency, S-parameters are mostly used for networks operating at radio frequency and microwave frequencies where signal power and energy considerations are more easily quantified than currents and voltages.
S-parameters change with the frequency are readily represented in matrix form and obey the rules of matrix algebra. Maxwell's displacement current that couples the electric and magnetic fields is significant and thus taken into consideration.
The vector wave equation, i. An antenna is a transducer that transmits or receives electromagnetic waves. In other words, antennas convert electromagnetic radiation into electric current, or vice versa.
Antennas generally deal in the transmission and reception of radio waves, and are a necessary part of all radio equipment.
Antennas are used in systems such as radio and television broadcasting, point-to-point radio communication, wireless LAN, cell phones, radar, and spacecraft communication. Resonance is the tendency of a system to oscillate with larger amplitude at some frequencies than at others. Antenna Design Programs--With surface mount technology and microcircuitry, most hams no longer build their own equipment. One area that is still open to amateurs is in antenna building.
For a hundred years the amateurs have made more breakthroughs in antenna design than the professionals. We do not know all the rules so we go ahead and build the antennas anyways, Some work, some don't. You may be that designer. If not, you will still have the satisfaction of working that DX with a homebrew antenna. Hams go where no engineer has gone before. To get you started, I have made up programs that cover the most common types of antennas and a few experimental designs.
Click on the icons to download. The programs do not write to the Windows registry so just delete the files when you no longer wish to keep them. Also some European machines use a comma instead of the decimal point. The program will give an error 13 when you try to compute. They require numbers like Most programs have inch and metric calculations.
There are few construction details here. I am a builder not a writer.
