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:

Antenna Magus launch story

Thursday, July 2nd, 2009

The Antenna Magus product launch went extremely successful, well nearly too successful we thought…

Antenna Magus was launched on the 1 May 2009. The date had been fixed months before and we had to GRIND to meet this deadline. Little did we realise that the 1st was a Friday and probably not the best day of the week to launch a new software tool!? And due to some unforeseen errors the website only went live on Saturday around lunch time.

Emails were sent out on Friday morning 1st of May at approx 9am to? +- to 20 000 recipients inviting the whole EM microwave world to go check out:

“the first antenna design software tool of its kind.”

It was a slow start (which probably gave the web server a chance to find its bearings) but surely the web traffic steadily increased and so did the free evaluation downloads. Early Monday morning it appeared as if someone was downloading the internet from our server! 100s of MB’s every minute! We thought this must be a bot that is crawling our site, trying to suck the life from our web server in Germany. So we checked with CST and FEKO,? (who link directly to our server to download the Antenna Magus installs) and they suggested that the traffic was genuine – people who just got an email announcement and had downloaded the evaluation version.

By Monday 5pm there were already 500 downloads of the evaluation version and nearly 300 views of the marketing video (which I’ll blog about a bit later) . By now the number of daily evaluation downloads has stabalised and the sales are starting to roll in…and we haven’t stopped smiling since.
