Vacuum Metallization: Does it degrade antenna performance ?

Hi All

Is it possible to design a Bluetooth headset (2402 to 2480 MHz), where the antenna could be an printen inverted-F antenna and the plastic surrounding the PCB has been vacuum metallization (to give the headset metallic look) ?

What I mean is: does the vaccum metallization degrade the antenna performance (ex in terms in lower antenna efficiency) and is it possible to transmit through the vacuum metallization ?

Any metal will block the antenna. So the answer is yes,
there will be a degradation on performance of the antenna.
I once faced a similar problem designing an
embedded antenna where the designer wanted a
metalic look on the product, to do that the paint was
metallized with the consecuently degrading on
performnace.
