Radiation pattern/antenna diagramm for Sparkfun UHF RFID Antenna (WRL-14131)?

Dear folks,

I’m working with the mentioned antenna for localization purposes and have been wondering, if there is any information about its radiation pattern (e.g. polar diagram)?

Furthermore, does anybody know what the antenna looks like inside? I could open it up but I’m afraid it’ll damage the antenna irreversibly…

Thanks and happy holidays!

Thanks for posting your question hjung!

Unfortunately we don’t have any data that has a radiation pattern on it for these antennas but the photo below shows what they look like inside. The antenna in the photo was defective though, the silver plate on the bottom with the brass standoffs would normally connect to the small brass pins on the PCB above.

Hope this helps you!
