Can someone tell me about double sided teflon boards or give me some data sheet about its? if anyone knows some Manufacturers, please tell me too. Thank you a lot!!
panel sectorial antenna
Hi people, i need to design a 90° (or 60°) panel antenna (microstrip fix) but i can´t to get specific information about this kind of antennas. anyone could give me some infirmation about this? thank you a lot
Hello , some one have information about calculations of wind resistance in parabolics reflectors? actually i´m workinng a 1,2 mts antenna and i`m want to know how to make a good structure for this antenna. :)
thanks a lot!!

Zin in a patch antenna.
Hello people!! i need to calculate the Zin (impedance at the edge) in a simple rectangular patch but i'm very confused because y have some diferent papers and they give me diferentes formules, so a get diferents results... anyone knows the correct form to calculate it...
probe feed port in ie3d
hello people: actually i need to feed a patch array structure with a probe feed, but i´ve a problem. My sustrate is h=5mm so i have to set: start Z coordinate=0, end Z coordinate=5 (in the Probe-Feed to Patch dialog), but i don´t konw what exactlly means "positive...
ok, may be i´m having a big conceptual mistake :? ... here i post two geo files, one with a strip line and one with a probe feed.. please take a look... thank you eirp!!

Hello people!! actually i have a problem: when i use a 50 ohm strip line (with a "50 ohms for waves" port ) to feed the structure i get a result, but if i use a "probe feed" port (which have Zc=50 ohm to, i think) in the same point , i get a diferent result (an important diference)... they have...
hello people. Actually i´m working in a 16 patch array antenna but i have some problems. firts of all, i´m using a 8 patches array (because the simulation time is too much in my Pc...)which is the half of the final array which i want to get. The resonant frecuency will be the sames for a 16...
