Reading between the lines, you might be referring to an antenna pattern polar graph, which sorta looks like a Smith Chart while one is under the influence of controlled substances. does this follow the rule of many 'simple' transducers, in that the same chart exactly models the sensitivity of the same antenna for reception? Antennas do not have a sensitivity spec. That's in the receiver. All antennas do is direct the RF in some particular direction, sometimes concentrating it, which is called gain. Antennas do not produce, amplify, or "strengthen" RF. The only re-direct it. I think you might need some help in basic RF buzzwords. It's helpful when we're both using the same terms to discuss the same phenomenon. Google finds several RF glossary lists online. Start with "A" and work your way to "Z" trying to absorb and understand as many buzzwords as possible. I do that when I initially approach a new technology and recently had to do it for optical terminology, of which I know little. If successful, we might then be able to decode what you're asking. http://micro.apitech.com/glossary.aspx http://e-meca.com/tech_papers/glossary.php http://www.amphenolconnex.com/support/glossary I'm hoping it does, otherwise life might get complicated. ![]() Hope is a poor substitute for understanding.
