A wireless electrical energy transmission system is provided. The system comprises a wireless transmission base configured to wirelessly transmit electrical energy or data via near field magnetic coupling to a receiving antenna configured within an electronic device. The wireless electrical energy transmission system is configured with at least one transmitting antenna and a transmitting electrical circuit positioned within the transmission base. The transmission base is configured so that at least one electronic device can be wirelessly electrically charged or powered by positioning the at least one device external and adjacent to the transmission base.

An electronic device is provided. The electronic device includes a tunable component and a first source follower circuit. The tunable component is electrically connected to a circuit node. The first source follower circuit is electrically connected to the circuit node. The first source follower circuit includes a first control terminal and a first terminal. The first control terminal is electrically connected to the first terminal.

The system for an antenna assembly for use on unmanned underwater vehicles (UUV). The antennas are low-cost, lightweight, single-use, and have a small form factor amenable to use on a micro-UUV. A central post and pivotally attached arms form an antenna (e.g., a monopole) that is lifted via an aerial, kite, or the like, when deployed from the UUV to extend the line of site of the antenna several meters above the surface of the water. In some cases, the antenna may be used on a number of UUVs in a swarm formation.

An electronic device is provided that includes a first housing including a first conductive region with a first slot structure that extends to a first edge of the first housing. The electronic device also includes a second housing movable with respect to the first housing and including a second conductive region with a second slot structure that extends to a second edge of the second housing. The electronic device also includes a wireless communication circuit that feeds power to a point on the first slot structure. The wireless communication circuit receives a first signal on a first electrical path including the first slot structure while the first edge and the second edge are spaced apart from each other, and receives a second signal on a second electrical path including the first slot structure and the second slot structure while the first edge is in contact with the second edge.

An electronic device is provided. The electronic device includes at least one hinge device, a plurality of housings that are foldably connected to each other via the at least one hinge device and configured to at least partially define a rolling space in a rolled state, a flexible display supported by the plurality of housings and disposed to be visible from the outside in the rolled state, a cavity defined to have a predetermined spatial volume through a conductive material in a first housing among the plurality of housings, wherein the cavity includes a slit that is at least partially connected to the outside, and a wireless communication circuit disposed in an inner space of at least one housing among the plurality of housings and electrically connected to a first point within the cavity, wherein the wireless communication circuit may be configured to form a radiation pattern through the cavity structure.

Techniques for antenna configuration for a foldable device are described and may be implemented via a wireless device to adapt to a variety of different wireless scenarios. For instance, configuration of an antenna system of a wireless device is adapted to optimize wireless performance in different physical configurations, such as open configurations and folded configurations. Generally, the described techniques optimize performance in different frequency bands based on changes in device configuration between open positions and folded positions.

A flexible antenna may be used to transmit information from and receive information to an information handling system by folding the antenna into contact with an inside surface of a display chassis of the information handling system, an outside surface of the display chassis and the surface connecting them. The folded antenna configuration may permit the antenna to receive and transmit signals in any or almost any direction when the chassis (e.g., a laptop) is in an open position even though the antenna occupies only a very small space of the inside surface of the display chassis (i.e., permitting the screen to occupy nearly all of the inside surface of the display chassis without interference from the antenna) or in a closed position.

Disclosed herein are antenna boards, antenna modules, and communication devices. For example, in some embodiments, an antenna module may include: an antenna patch support including a flexible portion; an integrated circuit (IC) package coupled to the antenna patch support; and an antenna patch coupled to the antenna patch support.
