Antenna Magus 2018.0 Released!

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.

and the new antennas are:

  1. Quad-ridged conical horn antenna (QRFH)
  2. Pyramidal horn antenna with spherical Luneburg lens
  3. Pyramidal horn antenna with cylindrical Luneburg lens
  4. 2-by-2 array of sequentially rotated wire helix antennas
  5. Planar elliptical dipole antenna

Folded Dipole – bent and twisted…

October 7th, 2015

Antenna Magus simplifies the task of choosing a suitable antenna. Of course if you simply need a structure that will radiate at a certain frequency – without a specific pattern or impedance requirement – the task is a lot simpler!

I have seen a number of articles and papers where the possibility of using logos as antennas is considered – most notably Apple in the iPhone and Macbook following the 2010 “Antennagate”  scandal. Designing a ‘logo-antenna’ seems quite straight-forward:

1.  Figure out how big the structure should be
2.  Figure out how to excite the structure

… and then see if it radiates efficiently.

How do you go about doing this for a general logo though? If you can start from a well-known antenna that has a similar structure or shape to the logo then (even without extensive EM and antenna knowledge) the principles and guidelines of  the known radiating structure can probably be used as a good starting point to determine how to achieve some form of semi-efficient radiation for the logo.

btfd_3D

To illustrate, we have done a simple investigation using the official Magus logo. The “known” Folded dipole antenna can be morphed into a structure resembling the Antenna Magus logo… essentially a bent and twisted folded dipole. Starting from the Folded dipole designed at 1 GHz (courtesy of Antenna Magus) the “logo-antenna” above was designed.

btfd_s11

And how does this “logo-antenna” perform… quite well! At the 1 GHz centre frequency, the reflection and radiation performance is comparable to the original Folded dipole, with a 14% (-10 dB) reflection bandwidth and a gain of 2.3 dBi at the centre frequency. Nice!

And what about other well known logos?

Some are easy:

While some of the best known logos such as Nike, Coca-Cola and Ford are not that easy to match up… any ideas?
