The first 80 contract hours worked for you within the month of September 2009 will be charged at 20% below the normal rate. You are warmly invited to take advantage of this offer, irrespective of whether you are an existing customer or a new customer!

Year-end 2008 - 2008 was a year with satisfactory business results. We have welcomed some new customers who are active in the field of remote sensing, with very interesting projects going on. In 2009, ElegAnt Solutions will celebrate its 5th anniversary and it is with confidence that we look forward to the new year. If necessary in this time of economic downturn, we have sufficient reserves available. As a client you can be assured of continuity. ElegAnt Solutions wishes all of its customers and other relations a successful new year, with many creative ideas and challenging new wireless projects!

May 2008 - Two new library investments of ElegAnt Solutions:


Ghavami, Michael and Kohno: Ultra Wideband signals and Systems in Communication Engineering (Wiley 2007)
Allen, Dohler, Okon, Malik, Brown and Edwards: Ultra-wideband Antennas and Propagation for Communications, Radar and Imaging (Wiley 2007)

February 2008 - Already for some time, ElegAnt Solutions is gaining insight in, and experience with, the design of multi-octave, omnidirectional (ultra) wideband antennas. Antennas for instance for the transmission or reception of DVB-T broadcasts in the higher VHF and UHF range between 200 and 850 MHz, or antennas for UWB pulse communications in the GHz range.

Often, antenna designs are called wideband or broadband as soon as they exhibit a low return loss over a wide range of frequencies (e.g. logperiodic antennas, the discone antenna, the biconical or spherical dipole). However, it is also important to consider issues like dispersion and radiation pattern. Biggest challenge in designing good multi-octave wideband antennas is suppression of higher order resonance current distributions. Multiple current maxima along the antenna body cause frequency dependent sidelobes in the radiation pattern of the antenna. The broad main lobe for lower frequencies splits up into multiple sidelobes. This may result in unwanted effects such as coverage problems on particular higher-frequency DVB-T channels, or angle dependent UWB pulse distortion.
Condition number one for a true frequency-invariant antenna is that its structure should be self-similar. Therefore there is a natural link to fractal geometries. Certain fractal structures excited as antenna indeed suppress higher order resonance modes, such as the Sierpinski gasket dipole (picture). This is one of the antenna structures currently under study at ElegAnt Solutions.

November 2007 - ElegAnt Solutions celebrated its 3rd anniversary in September (2007), and is currently working a.o. on the design of special antennas for UHF RFID application. 

September 2006 - Some recent investments of ElegAnt Solutions:


Novex P-20 Binocular microscope
Weller WSL Soldering station with WMP precision soldering iron

May 2006 - As from July 1, 2006, ElegAnt Solutions will discontinue its stepped tariff structure for antenna & RF design. All contracts with a starting date after July 1 will be based on a single and fixed hour rate.

December 2005 - The number of RF design jobs granted to ElegAnt Solutions showed a strong revival in the last quarter. Most of the jobs involved the development of integrated antennas for applications where the space available for antennas is very limited. Own development: compact directional antennas for 5 GHz WLAN following IEEE802.11a (picture).

August 2005 - ElegAnt Solutions has entered a business partnership with translation agency Krivaja Translations (www.krivaja.nl) to work together offering swift and high-quality translations English to Dutch and German to Dutch to publishers of technical/scientific texts (textbooks, magazines, manuals).
