Isn't waveguide kind of big at 13.56 MHz?
John forgive me, but I don't understand what you mean. Massimo |

Massimo Well, you said: "VSWR COPLANAR WAVEGUIDE 50 OHM 13.56 MHz = 1.0250 1 GHz = 1.1698 3 GHz = 1.3500" Maybe I don't understand coplanar waveguide, but I thought it would have to be really big to fit 13.56 MHz inside.

I sent Massimo direct mail asking if he really meant 13.56 MHz. He
responded, YES! I still wonder if he is having a language problem understanding MHz and GHz!! John Smith wrote: "Massi" wrote in message ... Isn't waveguide kind of big at 13.56 MHz?

SNIP So, it is a fact that English is not my language, but when I say MegaHertz I mean MegaHertz (= 1000000 Hz). Massimo, no offense was intended. I was just looking to make sure you meant MHz. Sorry if my post offended you. If so I ask your forgiveness. Deacon Dave SNIP |

...asking if he really meant 13.56 MHz... "John Smith" Yes, GHz would make much more sense. Except that 13.56 MHz is a very, very well known (common) ISM frequency. ....well, perhaps not as well known as it might be... ;-) Amusingly, most of the 30 Google hits on "13.56 GHz" are errors where people have incorrectly assumed GHz for such RFID usage. Stripline at HF ?? Geesh... I supposed if you've got the 'real estate'. |
