Problems with electromagnetic interference

Hello there,

we use the DW1000 on self-designed PCB`s for a tranceiver and a receiving anchor which work in TDOA.
In order to fullfill certain EMC-compliances, we found out, that we are facing problems when having electromagnetic interference between 24MHz and 74MHz radiatet at the device.
The result is, that we have no radio-connection between the two devices.
Here is a picture of the pcv-design on the transceiver.

Is it possible to receive the disturbing waves throug the UWB-Antenna, which the causes the DW1000 not working properly anymore?
We where thinking of using frequency-filters between the Antenna and the DW1000.
Did anyone ever faced problems like this?

Best Regards
