Examples disclosed herein provide for the exchange of signals wirelessly between devices. One example includes a first wireless communication unit of a first device and a second wireless communication unit of a second device. The example further includes a first magnetic member disposed within the first device to magnetically couple with a second magnetic member disposed within the second device when the first and second devices are to be placed within proximity of each other. The first and second wireless communication units may exchange signals between the first device and the second device over a wireless communication link formed by the magnetically coupled magnetic members.

The present disclosure discloses a WIFI antenna device, the WIFI antenna device includes a carrier, a grounding portion, a first radiation portion, a second radiation portion and a third radiation portion which all are provided on the carrier. The first radiation portion, the second radiation portion and the third radiation portion are coupled to the grounding portion. The coupling portion couples an electrical signal to the first radiation portion, the second radiation portion and the third radiation portion. The first radiation portion, the second radiation portion and the third radiation portion convert the electrical signal into the radiation signal. The first radiation portion determines a low frequency resonance point of a radiation signal emitted by the WIFI antenna device. The second radiation portion determines a first high frequency resonance point of the radiation signal. The third radiation portion determines a second high frequency resonance point of the radiation signal.

The present disclosure provides an ultra-wideband antenna for a reversible electronic device in a narrow space including: an upper half and a lower half; a hinge connected with the upper half and the lower half; a first RF signal source, loaded on the hinge; an electrical connection structure, placed on one side of the first RF signal source and electrically connected with the upper half and the lower half; a gapped groove, extending inwardly to the electrical connection structure along the outer side of the upper half and the outer side of the lower half; the hinge is spanned on the gapped groove; the hinge excites the gapped groove to form a first ultra-wideband antenna. While realizing the ultra-wideband antennas, it can also integrate with other multiple antennas, and their isolations are better than −10 dB, which basically meets the antenna performance requirements.

A power receiving device of a contactless power supply configured in a wearable electronic device having a main body coupled to a wearing member, can include: a power receiving antenna including one or more coils at least partially disposed on the wearing member; and where wires of the receiving coils extend substantially along a surface of a wearing member to form a coil turn that crosses through the surface of the wearing member or a surface of the main body in an axial direction.
