Flexible and modular antenna device with a flexible film substrate carrying at least one rf-module

A flexible and modular antenna device, comprising:

• a flexible film substrate with electrically conductive wiring structures,
• a first RF-module (RF:
• Radio Frequency) being arranged on the flexible film substrate, wherein the first RF-module is coupled to the wiring structures,
• wherein the first RF-module comprises:
• a first interposer being suitable for high-frequency use, the first interposer having a first RF antenna structure arranged on a first interposer surface,
• a first RF-chip arranged on the first interposer surface and configured to provide RF-signals to, or to receive RF-signals from, the first RF antenna structure and to translate the RF-signals into lower frequency baseband signals which are transferred along the wiring structures of the flexible film substrate,
• a plurality of contact pads arranged on the first interposer surface for electrically contacting the first RF-chip, the contact pads being electrically coupled directly to the first RF antenna structure via short conductor path structures, and
• vias extending through the first interposer between the first interposer surface and an opposite second interposer surface,
• wherein the first RF-module is mounted with its second interposer surface on the flexible film substrate, such that the vias connect the contact pads on the first interposer surface with the wiring structures on the flexible film substrate.
