RE: Circular patch behaves linear



Hi Tony

I built a dual band K5OE/K3TZ patch at
http://home.swbell.net/k5oe/dual-patch/dual_patch.htm

My version is shown at http://www.g6lvb.com/images/dualbandpatch001.jpg
where I spent a lot of time getting the measurements as accurate as possible
using vernier calipers etc.

FWIW I put it on a network analyser a friend of mine has and achieved these
plots without any tweaking at all:
http://www.g6lvb.com/images/patch001.gif 13cm patch 0 to 3GHz
http://www.g6lvb.com/images/patch002.gif 13cm patch 2151 to 2651MHz (2401MHz
centre)
http://www.g6lvb.com/images/patch003.gif 23cm patch 1019 to 1569MHz (1269MHz
centre)

Sadly I did not try them fitted to a dish.

Sadly I had not tried them
