SR150 Antenna Design and Tracks Length Tunning

[hs_turen]

Hi Everyone,

We are using murata uwb module(Type2BP) include sr150 and we want to developing custom board using this module. However we couldnt learn important information for antenna design from murata team. We have some questions to be sure about antenna design. Could you please answer our questions?

1. Should we lay a ground polygon on any layer under the UWB antennas area? 
2. If we will use gnd poligon on uwb antenna area, should we poligon cut-out under uwb antenna tracks?
3. What is your recommended clearance betweeen ground and UWB-BLE antenna tracks?
4. Is 4 layers pcb enough custom board?

Best Regards.

Hello,

Hope you are doing well. Sorry for the inconvenience this might cause you but as the information of these products it's under NDA (Non-Disclosure Agreement) the information it's not public.

I apologize, but as you are using a module/kit from a Module Maker (MuRata), you would need to redirect your questions to them, as they should be supporting their kits.

I really apologize for the inconveniences this might cause you, but the support path for this is through the Module Makers.

Best Regards,

Ricardo
