## Abstract

Some demonstrative embodiments include apparatuses, devices, systems and/or methods for controlling an antenna scheme of one or more antennas. For example, a controller may be configured to control an antenna scheme of one or more antennas of a mobile device for wireless communication based on a position of a lid of the mobile device relative to a base of the mobile device.

## Background
BACKGROUND
A mobile device, e.g., a laptop computer, a notebook computer, an Ultrabook computer, a tablet computer, a tablet personal computer (PC) or the like, may be able to communicate via one or more antennas.
The mobile device may include a base and a lid. For example, the base may include, a keyboard, a hard disk drive, and/or a touch pad, and/or the lid may include a display, a touch screen, and/or webcam.
The lid may be movable between two or more positions with respect to the base.
In a first example, the lid may be movable between an open position, e.g., when the lid is at an angle of about 90 degrees with respect to the base, and a closed position, e.g., when the lid is at an angle of about zero degrees with respect to the base.
In a second example, the lid may be movable between the open position and a detached position (“tablet position”), in which the lid is detached from the base.
In a third example, the lid may be movable between the open position, and a folded position (“tablet PC position”), in which the lid is folded over the base.

In some demonstrative embodiments, using the same antenna scheme of antennas 107 for wireless communication for the different positions of lid 114 may not be effective and/or efficient.
For example, device 102 may be able to communicate efficiently with device 104 using an antenna scheme, when lid 114 is at the open position. Device 102 may not be able to communicate efficiently with device 104 using the same antenna scheme, e.g., when lid 114 is at the closed position.
Using the same antenna scheme may not be efficient due to a change in the directionality of antennas 107 resulting from the change of the position of lid 114. The change of directionality may degrade a performance of antennas 107 and/or may not enable device 102 to communicate efficiently with device 104.
In some demonstrative embodiments, device 102 may include a controller 112 to control the antenna scheme of antennas 107, based on the position of lid 114 with respect to base 116, e.g., as described below.
