A printed circuit board (PCB) has electronic components of an electrical circuit mounted thereon. The PCB includes a wire that is coiled through the PCB one or more turns to form a coil of an inductor or an antenna that is integrated with the PCB. The PCB can include a cutout for accepting an inductor core. The shape and/or size of the inductor core can be varied to achieve a target inductance. Both ends of the wire can be electrically connected to corresponding nodes of the electrical circuit. One end of the wire can be electrically connected to a node of the electrical circuit, and the other end of the wire can be electrically connected to an antenna body.

Printed circuit boards with integrated inductors and antennas

A circuit board has an edge connector with signal traces. The signal traces are formed on a dielectric layer of the circuit board. A reference trace is formed within the dielectric layer or on another surface of the dielectric layer. Parameters of the reference trace are adjusted to set an impedance of a single-ended signal trace or a differential impedance of two adjacent signal traces.

Setting the impedance of signal traces of a circuit board using a reference trace

A circuit board has an electrical circuit and a connector that is attached to the circuit board. The connector has metal contacts. A housing of the connector has an embedded reference metal layer that is disposed under a single-ended metal contact or differential metal contacts. The reference metal layer sets the impedance of the single-ended metal contact or the differential metal contacts.
