In some demonstrative embodiments, antenna 107 may be coupled to hinge 112.
In some demonstrative embodiments, hinge 112 may be configured to allow rotating lid 114 between first and second rotational states with respect to base 116.
In some demonstrative embodiments, the first state may include an open state, at which a first angle, e.g., of about ninety-degrees, is formed between lid 114 and base 116, and the second state may include a closed state, at which a second angle, e.g., of about zero degrees, is formed between lid 114 and base 116.

In some demonstrative embodiments, coupling a single radiation antenna to hinge 112 may result in reduced wireless communication performance and/or efficiency. For example, rotating lid 114, may affect a directionality of a radiation pattern of the single radiation antenna, which may result in the single radiation antenna not being able to communicate, e.g., when lid 114 is at the open state and/or the closed state.
In some demonstrative embodiments, antenna 107 may include a dual directional wireless communication antenna, which may be configured to communicate wireless signals in a first direction, when lid 114 is at the open state, and to communicate the wireless signals in a second direction, different from the first direction, when lid 114 is at the closed state, e.g., as described below.

As shown in FIG. 2A, extended board layer 213 may be located on top of board layers 211. As shown in FIG. 2B, extended board layer 213 may be sandwiched between board layers 211. As shown in FIG. 2C, extended board layer 213 may be located at a bottom of board layers 211. A position of extended board layer 213 respective to board layers may be determined, for example, according to architecture and/or design considerations.

As shown in FIG. 2D, if the extended board layer 213 is formed of a rigid material, RF module 200 may be positioned at a predefined tilt angle, e.g., such that antenna 207 may positioned at a predefined required tilt angle.
In some demonstrative embodiments, extended board layer 213 may be formed of a flexible material to enable bending antenna 207 to form a predefined angle with a reference element, e.g., as described below.
Reference is now made to FIG. 3, which schematically illustrates a configuration of an RF module 300 including a rotatable antenna 307, in accordance with some demonstrative embodiments.

As shown in FIG. 3, utilizing flexible extended board layer 323 may enable fixedly rotating antenna 307 to a desired tilt angle by bending a portion of flexible extended board layer 323.
In some demonstrative embodiments, bending flexible extended board layer 323 may require more space for implementation, e.g., due to the 3 dimensional (3D) shape of flexible extended board layer 323. However, bending flexible extended board layer 323 may enable a relatively lower operating frequency, and/or a relatively greater directional gain, which may provide an advantage for antenna design. For example, bending flexible extended board design 323 may utilize the 3D structure of a chassis of device 102 (FIG. 1) to maximize a performance of antenna 107 (FIG. 1).
As shown in FIG. 3, flexible extended board layer 323 may be bent to form a predefined angle 317, denoted θ, between board layers 311 and antenna 307.

For example, mobile device 400 may perform the functionality of device 102 (FIG. 1), lid 414 may perform the functionality of lid 114 (FIG. 1) and antenna 407 may perform the functionality of antenna 107 (FIG. 1) and/or antenna 307 (FIG. 3).
As shown in FIGS. 4A and 4B, mobile device 400 may include a base 416, which is connected to lid 414 by a hinge 412. For example, base 416 may perform the functionality of base 116 (FIG. 1) and hinge 412 may perform the functionality of hinge 112 (FIG. 1).
As shown in FIGS. 4A and 4B, antenna 407 may include or may be included as part of an RF module 420, which is located within hinge 412. For example, RF module 420 may perform the functionality of RF module 300 (FIG. 3) and/or RF module 110 (FIG. 1).
As shown in FIGS. 4A and 4B, antenna 407 may be positioned at a predefined angle 417, e.g., corresponding to angle 317 (FIG. 3). Angle 417 may be determined such that antenna 407 may conform to a shape of hinge 412, e.g., to enable fitting antenna 407 within or on hinge 412.
In some demonstrative embodiments, angle 417 may be determined to maximize a performance of antenna 407, e.g., when lid 414 is at the open and closed states.
As shown in FIG. 4A, an angle of about zero degrees is formed between lid 414 and base 416, when lid 414 is at the closed state. Antenna 407 may radiate radiation pattern 426 in a first direction, e.g., a backward direction with respect to lid 414. For example, antenna 407 may radiate at the backward direction due to reflections of mmwave wireless communication signals from a metallic material, e.g., which covers base 416 and lid 414.
As shown in FIG. 4B, lid 414 may be rotated to the open state, e.g., at which an angle of about ninety degrees is formed between lid 414 and base 416. RF module 420 and antenna 407 may rotate to a position, which is substantially orthogonal to a position of RF module 420 and antenna 407 at the closed state, e.g., by rotating lid 414 from the closed state to the open state.
As shown in FIG. 4B, antenna 407 may radiate radiation pattern 428 in a second direction, e.g., a forward direction with respect to lid 414. For example, RF module 420 may radiate at the forward direction due to reflections of mmwave wireless communication signals from one or more objects below base 416, e.g., a table or legs of a user of mobile device 400.
As shown in FIG. 4B, when lid 414 is at the open state, the user, e.g., facing mobile device 400, may be able to utilize mobile device 400.
As shown in FIG. 4B, antenna 407 may be able to radiate radiation pattern 426 through a gap, which is defined between lid 414 and an upper body of the user. The gap may enable mobile device 400 to communicate over the mmwave wireless communication band.
In some demonstrative embodiments, RF module 420 may utilize a beamforming algorithm to form a relatively high directional gain of antenna 407, e.g., when antenna 407 is at different positions, which may enable mobile device 400 to communicate over the mmwave band and to establish a mmwave wireless communication link.

As shown in FIG. 6, metal layer 601 may include antenna 607 and a feeding line 603 to antenna 607.
As shown in FIG. 6, antenna 607 may be designed as a slot loop on metal layer 601. In other embodiments, antenna 607 may be designed utilizing different designs, e.g., a patch design, a slot design or any other suitable shapes.
Reference is now made to FIG. 7, which schematically illustrates a dual directional radiation pattern 700 of a dual directional wireless communication antenna, in accordance with some demonstrative embodiments.

Reference is made to FIG. 8, which schematically illustrates a method of communicating via a dual radiation antenna, in accordance with some demonstrative embodiments.

As indicated at block 802, the method may include rotating a dual directional wireless communication antenna, which is coupled to a hinge connecting between first and second elements of a device, by rotating the first element between first and second rotational states with respect to the second element. For example, antenna 107 (FIG. 1) may be rotated by rotating lid 114 (FIG. 1), e.g., as described above.
As indicated at block 804, rotating the first element between the first and second rotational states may include rotating the first element between an open state at which a first angle, e.g., about a ninety-degree angle, is formed between the first and second elements, and a closed state at which a second angle, e.g., a zero-degree angle, is formed between first and second elements. For example, lid 114 (FIG. 1) may be rotated between the open state and the closed state, e.g., as described above.
As indicated at block 806, the method may include communicating by the antenna wireless signals in a first direction, when the first element is at the first rotational state.

As indicated at block 810, the method may include communicating by the antenna wireless communication signals in a second direction, different from the first direction, when the first element is at the second rotational state. For example, device 102 (FIG. 1) may communicate via antenna 107 (FIG. 1) wireless communication signals directed to a second, different, direction, e.g., opposite to the first direction, when lid 114 (FIG. 1) is at the open state, e.g., as described above.
As indicated at block 812, communicating by the antenna wireless signals in the second direction may include communicating the wireless communication signals directed to an opposite direction to the first direction.
