6 Proximity to Dielectric Materials
Dielectric materials (like plastic or FR-4) detune an antenna by lowering its resonant frequency. The effect is not
as serious as placing an antenna next to metal objects and can be corrected by reducing the length of the
antenna. Therefore it is important for the antenna to be tuned when it is in the product. This is done during the
development of the product.
