Conductor board with a high frequency component

摘要

The board has a high frequency unit (17) e.g. electromagnetic resonator, provided in an insulating layer (1), where the electrical conduction (9) of the high frequency unit runs over the insulating layer. The insulation layer is thin, and another insulating layer (2) is provided for reinforcement of the former insulation layer. The frequency unit is included in a hollow space (8) in the latter insulating layer. A recess is formed in a metal layer (4) on a top side of the latter insulating layer, and a metal shield is provided on the top side of the latter layer, which shields the recess.
