Hello!
I want to ask for advice.
Is it important to use, for examle, GSM rf module with related 2 band antenna or I could also use some wideband structure, which covers both of bands?
Maybe somebody know if these unnnecessary bands are filtered in rf modules?
Thanks!
Thank you!
So that's why it's possible to connect such kind of dipole antenna as well?
**broken link removed**
Then the grounded part of antenna and the cable will also participate in radiation if it is conntected to an unbalanced input like here?
And therefore characteristics of the...
Ok, it is an asymmetric dipole antenna. But then How it is possible to connect it to wireless modules with unbalanced inputs? Like here:
I thought that it is possible for monopole antennas. Or an antenna has a balun structure somewhere?
A datasheet of this antenna could be found in https://www.lairdtech.com/WorkArea/DownloadAsset.aspx?id=2147483730
If you zoom in, we can see that the center conductor of the cable is connected to the structure above, but the bottom one to the outer braid of the cable.
Maybe this make any...
Hello!
Maybe you could help. How to distinguish what is monopole and what is dipole antenna in case of miniature standalone examples like:
Ok, the part closer to the wire seems to be a ground. But why it is so small? Is it some kind of DGS structure?
Thanks.
