Patent ID: 10490887

Abstract:
A method for producing an intermediate printed circuit board product (80) with an antenna structure (5), including steps of providing a ground layer (10) including optionally a release layer (20) that is removably positioned (22) on an antenna subarea (12) of an exterior side (11) of the ground layer (10); attaching a dielectric insulating layer (30) on the exterior side (11) of the ground layer (10) that is if applicable partly covered by the release layer (20); attaching a conducting layer (40) on an exterior side (31) of the dielectric insulating layer (30); laminating of the layers (10, 20, 30, 40) to receive a first semi-finished product (50); manufacturing of an antenna cavity (60) throughout the conducting layer (40) and the dielectric insulating layer (30) with a ground-plane area (62) that is if applicable made up of the release layer (20); attaching a compound signal layer (70) on the conducting layer (40) covering the antenna cavity (60); and laminating of the layers (50, 70) to receive the intermediate product (80).
