Description

Foldable electronic device including an antenna {FOLDABLE ELECTRONIC DEVICE INCLUDING ANTENNA}

Various embodiments of the present invention relate to a foldable electronic device including at least one antenna.

The use of electronic devices such as bar-type, foldable-type, rollable-type, or sliding-type smartphones or tablet PCs is increasing, and various functions are provided to electronic devices.

The electronic device can transmit and receive phone calls and various data with other electronic devices through wireless communication.

The electronic device may include at least one antenna to perform wireless communication with other electronic devices using a network.

A foldable electronic device may be operated with the first housing and the second housing in a folded or unfolded state around the hinge module.

The foldable electronic device may be operated in an in folding and/or out folding manner by rotating the first and second housings using a hinge module.

The foldable electronic device may have at least a portion of the first housing and/or the second housing made of a conductive material (eg, metal). At least a portion of the first housing and/or the second housing made of the conductive material may be used as an antenna (eg, an antenna radiator) for wireless communication. For example, the first housing and/or the second housing of the foldable electronic device may be separated through at least one segment (eg, slit) and used as at least one antenna.

When the first and second housings of the foldable electronic device are in a folded state, a conductive portion formed in the first housing and a conductive portion (eg, an antenna) formed in the second housing may overlap. In a foldable electronic device, conductive portions may be disposed adjacent to each other through at least one segment formed in the first housing. In the foldable electronic device, conductive portions may be disposed adjacent to each other through at least one segment formed in the second housing.

When the first housing and the second housing are folded, when the conductive portion of the first housing and the conductive portion (e.g., antenna) of the second housing overlap, the antenna function is lost due to the electrical components of the conductive portion of the first housing. The radiation performance of the conductive portion of the second housing may be reduced. In a foldable electronic device, when a first conductive part and a second conductive part (e.g., an antenna) separated by a segment of the first housing are placed adjacent to each other, the foldable electronic device performs the function of an antenna due to the electrical component of the first conductive part. The radiation performance of the second conductive portion may be reduced. The foldable electronic device includes a third conductive portion that functions as an antenna due to the electrical component of the fourth conductive portion when the third conductive portion and the fourth conductive portion separated by the segment of the second housing are disposed adjacent to each other. Radiation performance may be reduced.

If the radiation performance of the antenna deteriorates, the foldable electronic device may not be able to properly make phone calls and/or transmit and receive data with other electronic devices.

Various embodiments of the present invention use a matching circuit and at least one filter circuit to reduce the radiation performance of the antenna even if the conductive portions of the first housing and/or the conductive portions of the second housing overlap or are disposed adjacent to each other. A foldable electronic device that can prevent this from happening can be provided.
