As I mentioned in the last day or two, I'm more of a software person than a hardware person, so I may come across as a little slow on some things here ... this particular subject being one of them. The pictures of the wifi boards I've seen all show a thick linear antenna. I seem to recall that there are also flat square antennas out there (specifically, I once ripped apart a wavelan (previous name of "orinoco" 802.11b brand products) PCMCIA card and found a flat square antenna inside), but don't know much about them ... like how to make one if I can't find them pre-made and already using the same connector as the gumstix boards use for antennas. Does anyone know of such a thing that would work with the gumstix boards? I'm specifically thinking of something that is hopefully going to be less than 30mm x 30mm or so. (to build on my last post, I'm thinking of something that would take up less than half of the area of the bottom of an altoids tin, so I could have one for wifi and one for a 3g/gsm/gprs board ... not sure what I would need to do wrt bluetooth though; but the idea would be to drill some small holes either on the bottom of the altoids tin, or on the back (under the hinge), and then secure the antennas to the bottom surface... then put some sort of protective layer over it all (and then maybe cover that protective layer with a decal that looks like the original tin bottom).) |

Hi > I seem to recall that there are also flat square antennas out there > There are a bunch of specialist websites which are worth checking out (depends on which country you are in), but basically root around the commercial manufacturer suppliers and order some catalogues. Basically there is an absolute wealth of stuff out there - pick and choose. These guys have loads of fun toys if you are in the UK http://www.tdc.co.uk Good luck Ed W |

I was looking for GPS antennas the other day and some of the companies I found have a wide range of antennas. http://www.linxtechnologies.com/index.php http://lairdtech.thomasnet.com/category/antennas-and-batteries? http://www.hyperlinktech.com/index.php I didn't look to hard at the stuff just did some digging but I hope it helps.
