Description

Electronic devices including antennas and antenna devices

The present disclosure relates to an electronic device including an antenna and an antenna device.

There is an increasing trend of antennas being placed in electronic devices to communicate using various frequency bands.

As the thickness or size of electronic devices decreases and the number of electronic components included in the electronic devices increases, it becomes difficult to place antennas in electronic devices due to consideration of factors that affect antenna performance, such as ground.

When it is necessary to place a new antenna in an electronic device, a slot antenna is placed in the electronic device to facilitate antenna installation. However, due to the characteristics of the slot antenna, it is difficult to provide multiple frequency bands.

An electronic device and antenna device including an antenna according to one embodiment of the present disclosure can provide a slot antenna capable of supporting multiple frequency bands.

An electronic device including an antenna according to one embodiment of the present disclosure may include a housing including a front plate at least partially transparent, a rear plate at least partially opaque, and side members surrounding a space between the front plate and the rear plates; and a slot antenna spaced apart from the side members by a specified distance and forming an antenna structure with at least a portion of the side members. The slot antenna may include a slot antenna region including a slot having a specified length and a specified width; and a variable ground region including at least one switch and a plurality of ground lines, the variable ground region having a capacitance that changes by coupling with the side members depending on a combination of connections between the plurality of ground lines and/or the plurality of ground lines.

An antenna device according to one embodiment of the present disclosure may include a slot antenna region including a slot having a specified length and a specified width; and a variable ground region including at least one switch and a plurality of ground lines, the variable ground region having a capacitance that is changed by coupling with a conductive member disposed outside the plurality of ground lines according to a combination of connections between the plurality of ground lines and/or the plurality of ground lines.

An electronic device and antenna device including an antenna according to one embodiment of the present disclosure can improve communication performance of the electronic device by providing a slot antenna capable of supporting multiple frequency bands without changing the design of the electronic device.

An electronic device and antenna device including an antenna according to one embodiment of the present disclosure can save design costs of the electronic device by providing a slot antenna capable of supporting multiple frequency bands without changing the design of the electronic device.
