rf antennas
Hi all,
I am looking for rf antennas that could fit into a 1" by 1" plastic case, operating frequency 500Mhz. They could also be pcb antennas. Could you suggest me some places to lookfor? Thanks, Adam |

" I am looking for rf antennas that could fit into a 1" by 1" plastic case, operating frequency 500Mhz. They could also be pcb antennas. Could you suggest me some places to lookfor? Microstrip Antennas, D. M. Pozar, Proceedings of the IEEE, Vol. 80 No. 1, January, 1992, page 79 et seq Or go the Patent Office website (www.uspto.gov) and search for patents issued to Martin V. Schneider. 73 de W2GERry |

Insects had antenna millions of years before man ever walked the earth. In fact, the word "antenna" comes directly from the insect world and was adopted for RF antennas, because they reminded someone of insect antenna. -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

That certainly would explain why the plural of the two different types are
different. "Cecil Moore" wrote in message ... JOE wrote: What other sorts of antennas are there exactly? Audio? Light? Tactile? Thought they ALL were RF in nature.... could be wrong....

Nope, antennae only applies to bugs, the devices used to receive radio waves
are antennas. "Brenda Ann" wrote in message ... "W4JLE" w4jle(remove to wrote in message ... That certainly would explain why the plural of the two different types are different.

Actually I am not trying to design antennas ( 500Mhz to 1Ghz- I guess
this gives you information about what sort they are), I am trying to buy them on a pcb or small chips that could be mounted on a PCB. Thanks, Adam "JOE" wrote in message ...

My guess is that the plural for insect antennae came from Latin and the plural for RF antennas came from a more modern language. The word "antenna" entered the English language around 1646 from Middle Latin according to my dictionary. There were no RF antennas in 1646, at least not on purpose. -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |
