Antenna Magus 2018.0 Released!

Wednesday, December 13th, 2017

We are pleased to announce the release of Antenna Magus Version 2018.0 which sees a number of new features and improvements, as well as two new antennas.

Some of the highlights of this release are:

  • Over 325 antennas and transitions now available
  • Spatial Limitations can now be added as part of a specification. Antenna Magus will  determine whether the designed device will fit into the available space and which orientation will achieve the closest fit. The spatial limitations are graphically shown together with the bounding box of the device in order to visualise whether the device fits within the limits or not
  • Trace Names for 2D Radiation plots have been standardized to be in terms of ? and ?, in accordance with the Spherical Coordinate System and will simplify comparison of different devices in the Compare Window.
  • To aid the user in using Toolbox Calculators, the objective fields in all Toolbox Calculators are now pre-populated with default values.
  • In addition to the recently added zoom function in the model preview, it is now also possible to pan the preview model.
  • A planar triangular array has been added to the Array Calculator.

Version 2017.3 Released!

Monday, August 28th, 2017

We are pleased to announce the release of Antenna Magus Version 2017.3 which sees a number of small new features and improvements, as well as three new antennas.

Some of the highlights of this release are:

  • Three new antennas focusing on Wireless Body Area Networks (WBAN) bringing the total number of available antennas and transitions to 324
  • Improvements on existing antenna designs and export models, e.g. all offset reflectors can now also be designed for focal length to projected reflector diameter ratio.
  • Colour Picker allowing the user to change the colour associated with a design.
  • Compare Window allowing the comparison of designs for different devices.

Building and measuring Antenna Magus designs in the office

Monday, September 7th, 2009

Just before I left for IEEE AP-S and IEEE MTT 2009 in the States, I asked the engineers whether they could build a few prototypes that I could take with me. This was the Friday afternoon before I left. I had ordered some basic raw materials like copper tape, 5mm signage boards (with an Er of approx 1), small metal ground planes and a few of SMA connectors.

We turned the boardroom table into a workbench with soldering irons, metal cutting scissors, tape and so forth. I?d not seen the engineers so excited since the previous Foosball tournament! Each could pick an antenna of his choice, design it with Antenna Magus, run the simulation, build it and then measure the impedance on the network analyser. Some of the antennas we used were the Circular pin-fed linearly polarised patch, Inverted-F (IFA), U-slot dual-band planar inverted-F, Elliptical rectangular monopole, Suspended plate antenna (cut-out version) and the Discone. I also invited the software team and a few others who had never built their own antennas before and they were ecstatic to see how their measurements matched the Antenna Magus results.

We had a lot of fun and unlike other Friday afternoons, no one wanted to go home for the weekend (or perhaps it took a bit longer for those with less experience in mechanical construction).

Here are pictures of two antennas we built and measured:
