Samsung patents antenna design for foldable phones

This patent describes a method for placing wireless antennas on the metal frames of a foldable phone's two halves. It uses specific gaps and electrical circuits to allow the antennas to work while the device is folded or unfolded.

Why it mattersIt helps engineers solve the technical challenge of maintaining strong signal strength in devices that bend.

In the filing’s own words

A foldable electronic device is provided that includes a hinge module, a first housing coupled to a first side of the hinge module, a first printed circuit board disposed inside the first housing and including a first wireless communication module, a processor, and a first ground or a second ground, and a second housing coupled to a second side of the hinge module, in which the first housing includes a first segmenting portion, a second segmenting portion, a first conductive portion, and a second conductive portion, in which the second housing includes a second wireless communication module, a third segmenting portion, a fourth segmenting portion, a third conductive portion, and a fourth conductive portion, and in which a matching circuit is disposed between the first conductive portion and the first ground, and a first filter circuit is connected to a signal path between the first conductive portion and the matching circuit.

What exactly they claim (claim 1)

1. A foldable electronic device comprising: a hinge module; a first housing coupled at least partially to a first side of the hinge module; a first printed circuit board disposed inside the first housing and including a wireless communication module, a processor, and at least one of a first ground or a second ground; and a second housing coupled at least partially to a second side of the hinge module, and configured to be at least one of unfoldable or foldable with the first housing using the hinge module, wherein the first housing includes: a first segmenting portion, a second segmenting portion, a first conductive portion disposed between the first segmenting portion and the second segmenting portion, and a second conductive portion disposed between the hinge module and the second segmenting portion, and electrically connected to the wireless communication module, wherein the second housing includes: a third segmenting portion, a fourth segmenting portion, a third conductive portion disposed between the third segmenting portion and the fourth segmenting portion, and electrically connected to the wireless communication module, and a fourth conductive portion disposed between the hinge module and the third segmenting portion, and electrically connected to the wireless communication module, and wherein a matching circuit is disposed between the first conductive portion and the first ground, and a first filter circuit is connected to a signal path between the first conductive portion and the matching circuit.
