UDK Supported Antenna

Hi ,

Where can we get antenna designs that is supported for LC14 single antenna solution. Also, is there a list of supported high gain antennas available for CH9? Are there special provisions to make it compatible with PA/LNA for CH9.

We are trying to make a custom board and stuck at antenna selection.

Best Regards.

Hi,

do you looking for something like this?

Hi @foray ,
I tried to run Leaps RTLS in Murata 2AB Dev. Kit and in UDK1 (LC14)

SCENARIO A:
I tried to flash the leaps rtls in Murata 2AB Dev. Kit and make it a TWR Tag.

But when I use this setup with 4 UDK Anchors in TWR Mode, around 30% packets were constantly dropped ( ‘les’ command did not use to show all range from all 4 UDK Anchors ).

SCENARIO B:

I used 2 UDK Anchors and 2 Murata 2AB Dev Kit as another 2 anchors in TWR mode. Tag is EITHER Murata 2AB Dev Kit OR UDK Tag

In this scenario, The Tag is able to get distances from only UDK Anchors. The distances from Murata Dev Kit anchors are not showing up in the ‘les’ command. It only shows when i bring the tag nearby the Murata Dev Kit Anchor ( distance <3m )

INFERENCE:

I believe there is some issue maybe due to difference in Antennas of two different boards. Do we need to change some configuration when trying to run it in Murata 2AB Dev Kit ?

OR

While designing our own board for both anchor/tag, Do we need to stick with Jolie JL159 Antenna? In this case it is difficult to find reference design of Jolie Antenna online

Hi @cruizer
the main problem is that muRata 2AB dev kit contain a directional AoA/PDoA antennas. This means that you will always get a good reads only from one direction from the BOT side of the PCB. You can try to use 2AB dev as anchors but you need to position them carefully.
