An antenna of a wearable device includes a metal bottom housing of the wearable device, a printed circuit board, a metal middle housing that encircles the printed circuit board, and a communications circuit set on the printed circuit board. A slot exists between the metal middle housing and the metal bottom housing. The metal middle housing is connected to the metal bottom housing using a second connecting wire. The metal middle housing and the printed circuit board jointly serve as a ground plate. An antenna feed line is used to connect the metal bottom housing and the communications circuit module. The metal bottom housing serves as an antenna radiation body.

Wearable device and antenna thereof

The present embodiments disclose a wireless mobile device, including a metal frame, a circuit board disposed in the metal frame, where there is a slot between at least one side edge of the circuit board and the metal frame, a first grounding point is connected to the circuit board and the metal frame, a second grounding point is connected to the circuit board and the metal frame, and a feeding point is located between the first grounding point and the second grounding point and is connected to the circuit board and the metal frame; and each antenna open-circuit stub suspends in space on an outer side of the circuit board, one end is connected to the metal frame by crossing the slot, and a connection point of the antenna open-circuit stub and metal frame is located between the feeding point and the second grounding point.

Wireless mobile device

The present disclosure relates to communication technologies and discloses a method and apparatus for multi-antenna transmitting based on spatial-frequency encoding. The method includes: performing spatial-frequency encoding on input data and outputting encoded data; mapping the encoded data to the same sub-carrier of each antenna in an antenna group; adding a phase shift to the encoded data on different sub-carriers of each antenna; OFDM-modulating the phase-shifted encoded data on each antenna; and transmitting the OFDM-modulated data by transmit antennas.
