An antenna structure includes a first antenna with a first feed point feeding current, a first radiating portion, a second radiating portion, and a first ground point. The first radiating portion is electrically connected to the first feed point and receives radiation signals in a first frequency band. The second radiating portion is electrically connected to the first feed point and receives and sends radiation signals in a second frequency band. The first ground point is spaced apart from the first feed point and is electrically connected to the second radiating portion.

Antenna structure and wireless communication device using same

An antenna structure includes a feed portion, a ground portion, a first radiating body, a second radiating body and a third radiating body. The first radiating body is connected to the feed portion and configured to obtain a first resonance frequency band. The second radiating body is connected to the feed portion. The third radiating body includes a first connection section connected the ground end, a second connection section, and a third connection section perpendicularly connected between the first connection section and the second connection section. The first connection section and the second connection section are positioned at two opposite sides of the second radiating body so that the third radiating body and the second radiating body cooperatively obtain a second resonance frequency band.

Antenna structure and wireless communication device using the same

A wireless communication device includes a base board, a display module, and a metal member. The display module is located on the base board. The metal member includes a frame and a metal body. The frame surrounds the display module. The metal body extends from the frame, and is spaced from the display module to reduce electromagnetic interference between the at least one metal body and the display module.

Wireless communication device

A portable wireless communication device includes a connector configured to charge the portable wireless communication device by electronically connecting a power source to the portable wireless communication device. The connector includes a plurality of pins, one of the pins configured to serve as a radiation portion of an antenna to receive/send wireless signals when the connector electronically is uncoupled to the power source.

Portable wireless communication device

A wireless local area network adapter includes a housing, a printed circuit board, an antenna, at least one elastic sheet and a plug. The printed circuit board includes a first ground plane. The antenna is electronically connected to the first ground plane. The elastic sheet is positioned on the printed circuit board, and is electronically connected to the first ground plane. The plug includes a shell, at least one part of the shell made of metal, the at least one elastic sheet contacting the metal part of the shell for electronically connecting the shell.

Wireless local area network adapter

A wireless communication device includes a housing and an antenna assembly. The antenna assembly includes a base board, a feed member electronically connecting with the base board to carry an electrical current, and a radio member including a first radio portion, the first radio portion defining a first slot. The radiator couples with the feed member, inducing an electrical current in the first radio portion. The radio member is electronically connected to the base board through the metal housing, enabling the induced electrical current to flow through the first radio portion, the metal housing, and the base board to form a current loop. The induced electrical current flows through the first slot to excite a first resonance mode, enabling the antenna assembly to receive/transmit a first wireless signal.

Antenna assembly and wireless communication device employing same

A wireless communication device includes a metal housing, a baseboard, and a current feed member electronically connected to the baseboard to obtain an electrical current from the baseboard. The housing defines a first notch and a second notch communicating with the first notch. The housing couples with the current feed member, such that the first notch and the second notch both induce the electrical current to excite two resonance modes, the two resonance modes enabling the wireless communication device to receive and transmit first wireless signals and second wireless signals having different central frequencies.
