RF Antenna design and Metal Housing

[Andreas]

Dear All,

any opinion on attached antenna design (blue) to the outside of a metal housing?

• PCB that flows around an aluminium die cast housing
• External to aluminium housing there are plastic materials around PCB
• Antenna dimensions will be copied from nrf51-dk
• Any clearance requirements to metal housing...?

Thanks very much for your feedback in advance.

RF engineering is magic.

You will need to experiment and tune. While you might get some good ideas, you will not get a full solution just by discussing it here.

Ok, thanks for your feedback. True, RF is tricky, but I would like to avoid potential pitfalls in first board revision if possible. If there is an obvious nogo, I would appreciate your comment.
