International Classification:

H01Q 9/04
B29C 41/42
H01Q 5/35
H01Q 9/06

Abstract:

An antenna structure can include a printed circuit board module and a mold compound disposed on a side of the printed circuit board module. A planar antenna is defined by a conformal shield layer disposed on a first surface of the mold compound such that the mold compound is disposed between the printed circuit board module and the conformal shield layer. The thickness of the mold compound layer and the shape of the conformal shield layer can be varied to optimize a performance of the antenna.

International Classification:

H05K 3/46
H01Q 1/38
H05K 1/16

Abstract:

A method of making a printed circuit board structure including a closed cavity is provided. The method can include the steps of forming a cavity in a core structure of a core layer, laminating each of a top surface and a bottom surface of the core structure with an adhesive layer and a metal layer to prepare a laminate structure and cover the cavity to define a closed cavity. The method also includes forming vias through the laminate structure, and patterning the metal layers in the laminate structure.

Abstract:

Devices and methods related to nested filters. In some embodiments, a radio-frequency device can include a substrate, and first and second filter devices mounted on the substrate with respective support structures, such that at least a portion of the second filter device is positioned in a space defined by an underside of the first filter device and the support structures for the first filter device. Such a radio-frequency device can be, for example, a packaged module for use in an electronic device such as a wireless device.
