Antenna Magus

An Expert System for Antenna Design


Antenna Magus is a software tool to help accelerate the antenna design and modeling process. It increases efficiency by helping the engineer to make a more informed choice of antenna element, providing a good starting design. Validated antenna models can be exported to CST Studio Suite from a huge antenna database of over 330 antennas, which means that the engineer can get to the customization phase of an antenna design quickly and reliably.

Antenna Magus has proven to be an invaluable aid to antenna design engineers and to anyone who requires antenna models for antenna placement and/or electromagnetic interference studies.


Whether starting with a new design or updating an existing system, most antenna engineers will start with an antenna element that is well known. Antenna Magus makes it easy to explore alternative options.

The Antenna Magus database is continually being updated and released with new and improved antennas, models and designs so that engineers can efficiently explore their options and be confident that all their bases are covered.

In many cases it is only after the attempt to adapt and optimize an existing antenna element has failed to meet the new specifications that the engineer will start to consider other elements. Often, one of the first elements considered becomes the de facto choice, simply because too much time has been expended on the element choice and the "cost" to start over with a new element is too high.

To meet the need for rapid assessment of many antenna elements, antenna information in Antenna Magus is structured in a standardized format, making it easy to compare various elements identified using a keyword based search of the database. Unlike most literature, Antenna Magus highlights unique and general characteristics of each antenna which makes it easy to compare antennas with each other and, more importantly, to compare them with the given requirements.

When designing an antenna for the first time, there are some elementary steps that need to be completed before continuing with the distinctive (non-standard) part of the design process.

If one knows where to start the design process - i.e. which references to use and what data to compare first order designs to - the elementary steps should be trivial, but often the starting point is not that well defined. Published papers or books may have insufficient information that is needed to reproduce reference designs and often good reference results aren't available. This means that days are spent manually optimizing a basic antenna structure in an attempt to get the general performance within specification.

Antenna Magus takes care of this (sometimes tedious) exercise by offering reliable first order designs that have been validated against reference data. Each antenna is thoroughly researched and design algorithms undergo various tests and validation routines to confirm that they work properly for a wide range of objective combinations.

Antennas can be designed for specific objectives like gain, bandwidth and impedance at the puch of a button.

Estimate the performance

The "Estimate performance" feature allows quick analysis of the designed antenna to give an indication whether an element is a suitable candidate for the final design.

Because the topology and the environment of the antenna are known, Antenna Magus can make certain approximations which can speed up analysis time while still giving reasonable estimated performance results.

The user can study the relationship between certain physical parameters within given constraints and the antenna's performance within the structured Antenna Magus framework before proceeding to non-standard changes and additions to the antenna.

Design antennas for a given specification and estimate their performance

Antenna Magus' export functionality allows more time to be spent on antenna design and less time on mastering simulation software. Novel concepts and design ideas can be tested quicker than ever before.

Starting from "ready to run" parametric simulation models exported from Antenna Magus, users can leverage the capabilities offered by the supported 3D EM simulation tools more effectively. Models can also be combined to rapidly realize new topologies.

Efficient information management affects the bottom line of all companies, because it gives employees access to knowledge that has already been developed.

Although various information management systems exist (Sharepoint for documents, iTunes for music or Picasa for photos etc.), up until now there has not been an information management system designed specifically for antenna engineers. This has resulted in critical information being stored in stacks of papers, on CD's/DVD's or physical prototypes somewhere in a dusty store room. This knowledge represents years of experience and work - but is not very accessible or sharable. Much information is never stored and only exists inside an engineer's head. This means that a company can only retain its intellectual property as long as that engineer is available.

While creating Antenna Magus, it was necessary to create a database to manage all the information in a consistent manner. After many requests from Antenna Magus users, this content management system can now be accessed from within Antenna Magus by users. The content management approach has been specifically constructed for capturing and working with antenna information and refined over the years through extensive use.

This new feature provides engineers with a framework to store information like documents, sketches, design algorithms, measured data and models in a logical, accessible way. This framework is consistent for all antennas in the database which makes it easy to find information and compare different antennas. As more knowledge of a specific antenna is gained, the information can easily be extended and improved. Once the information has been captured, it can easily (and securely) be shared among colleagues or friends.

Antenna Magus is the most extensive antenna synthesis tool available on the market today. Its huge database of over 330 antennas can be explored to choose the optimal topology, which can be designed to meet the system criteria.

Used to store various design specifications in a structured format. These Specifications may subsequently be used in Find Mode (to help identify feasible antennas) as well as in Design Mode (to populate the Design Objectives of antennas in the Collection). A number of pre-defined specifications are included as part of the library. These pre-defined Specifications may be used as-is or expanded and refined by the user.

Specification Library | Antenna Magus

A collection of common designation standardized waveguides. It can be used to easily find the dimensions of a specific designation or to find the electrical characteristics of a standard guide. Cut-off frequencies, as well as usage frequency ranges are indicated in the library. Custom waveguides that may be in use in a company/industry can easily be added to the library for easy reference.

Contains an extensive list of commercial substrates and allows for the easy addition of user specified substrates. This eliminates the need to search literature or the internet for suitable substrates for a given antenna element. The substrate library is one click away and it conveniently filters the whole database of substrates according to specified physical or electrical properties

Contains a number of common coaxial RF connectors that might be used when modeling antennas. For each connector type, parametric export models are available for supported CEM tools.
