Clearance on all layers?
I am just designing a board with the Integra SR4L049-R antenna.

The Host PCB layout needs a clearance acording to the datasheet.
Is this clearance necessary on all layers or just the top layer where the antenna is?

And my board is just 60 mm in lenght... do I have a chance to get a signal nontheless?
Best regards

Hi Chris,

The clearance required is needed through all layers and is critical for the antenna to function correctly.

For a PCB length of 60mm this will need careful integration – but it is possible to get signal. Feel free to post your board layout here once it's finalised.
