Looking for good antenna designs

Post by blartin » Mon Jul 16, 2018 5:02 pm

Hi all, friendly greetings from Argentina.

I was wondering if there is a repository of good antenna designs for SDR with bladerf, or perhaps someone has any suggestion about a certain antenna of any kind.

Thank you

The AARL content is pretty decent - http://www.arrl.org/antennas. They're not SDR specific or anything but they cover broad enough topics that you should be able to find something to meet your needs. Do you have a particular signal type you're hoping to chase or transmit?

If you're looking for sort of do-it-all ultra wideband antennas that aren't costly check out RFSpace.

I've used an earlier version of their PCB Vivaldi slot antenna in an application that ranged from 900-3000MHz and it seemed to perform as spec'd. I'm very happy with it given it was ~$60. If it hadn't have been for RFspace I would have been forced to make my own antenna as comparable wideband antennas were incredibly expensive.
You can order their stuff through their amazon shop.

Of course, like the poster above, if you have a specific application in mind I may be able to recommend a product or design better suited for it.
