TIDC-SIGFOX-CC1120-CC1190-BP: Ti Sub-Ghz Kit Antenna Data

Hi,

I am evaluating Ti's Sun-1GHz CC1120-CC1190 boosterPack reference design for sigfox networks. I have modified the boards to make it operate at 868 MHz. So right now I am doing some performance testing with the boards in the field, whereby I am trying to seeing what kind of rssi values I am getting for different distances in different terrain settings.

One of the things is, the documentation for this kit doesn't have any details about the on-board pcb antenna.The reference design has the layout with the on-board pcb antenna, but I am looking for data such as the antenna return loss, does the antenna has gain, the radiation pattern for the antenna, etc. This will help me in terms of making more sense of my rssi values, knowing how to orient the board, etc

Is there any way I can get this data? Maybe one of TI's application engineers can get this data from the designer of the board?

All the files related to this kit are available at the below link:

Thanks,

Malcolm
