Antenna Magus workflow:

What makes Antenna Magus different to other antenna design software?

Antenna Magus is actually nothing like any other antenna design software product. It takes on a completely new approach to designing antennas. You may have seen other "Antenna design software" tools that are intended to assist engineers with antenna design but aren't really that useful since many of them consist of a very small selection of known antennas that can only be designed for a limited set of objectives over a small range of input parameters.

Another common misconception is that analysis software and antenna design software are the same thing. "Design" and "analysis" are in fact two completely different concepts which should not be confused. Analysis forms an important part of the antenna design process, but the design process consists of a number of steps to be completed before the antenna analysis and optimisation can start.

An Antenna Magus design case study:

Case study 1: 11 GHz Reflector antenna feed with dual polarisation

All antenna engineers are familiar with a number of antennas. For some it is only a handfull while some seem to have unlimited knowledge of different antenna types and an in depth understanding in the underlying physics of how they actually work. The bottom line is that not one person can know everything about antennas and that hands-on experience is probably the most valuable commodity in the field of antenna design. When faced with new design requirements most engineers will start with antenna topologies that they are familiar with.

Antenna Magus has revolutionized this first step in the antenna design process by broadening the scope of possible antennas that would be considered during the initial phase of design.

Let's look at a typical case where an antenna engineer or consultant needs to design an antenna for a specific system or application. Assume the client supplied the following specifications:

For this specific example, the engineer might enter "reflector feed" and "dual polarisation" in the Antenna Magus search dialogue, which would return a selection of antennas that match each combination of search terms. The following five antenna candidates are returned by Antenna Magus as potentialy suitable antennas adhering to both search terms:

Without any detailed understanding of any of these antennas, the engineer can use the "info doc" feature to gain a very good overview of each antenna. Antenna Magus describes each antenna in a well summarised document or "info doc" outlining basic specifications, adavantages and disadvantages of the antennas that might be worth considering for the design. It would become apparent that the Printed four arm sinuous antenna is more suitable for wide band reflector applications where narrow -10dB beamwidths are not required. Further insight that might be gained is that the Coaxial cavity horn is a great reflector feed as it provides a broad, almost-uniform illumination but it is better suited to deep reflectors with F/D < 0.35. After eliminating these two antennas the engineer can then further investigate the other three options suggested by Antenna Magus:

Information on these antennas can be compared using the Antenna Magus "compare" option in the information browser. A "side-by-side" view in which information is arranged and displayed as shown below:
