ANTENNA DEVICE

摘要

An antenna device, including a circuit board, electronic components, a functional component module, an antenna module and a feed line, is provided. The electronic components are disposed on the circuit board and include a microprocessor and a wireless communication chip. The functional component module includes a carrier and a metal member disposed on the carrier. The antenna module includes a feed point, a ground point and a radiator, the feed and ground points are disposed on the carrier and electrically connected to both sides of the metal member respectively, and the ground point is electrically connected to the ground layer of the circuit board. The radiator includes at least a part of the metal member, while the feed line can transmit a wireless signal to the feed point to feed into the radiator. Therefore, the metal member can serve as the radiator to conserve the space of accommodating another radiator.

主权项

1. An antenna device, comprising:
a circuit board, comprising a ground layer; a plurality of electronic components, being disposed on the circuit board and including a microprocessor and a wireless communication chip; a functional component module comprising a carrier and a metal member disposed on the carrier, the carrier having a main portion and an extended portion, a side surface of the main portion being spaced apart from and facing toward a side surface of the circuit board, and the extended portion extending from the side surface of the main portion to connect with the side surface of the circuit board; a first antenna module, having a feed point, a first ground point and a first radiator, the feed point being disposed on the main portion and electrically connected to a side of the metal member, the first ground point being disposed on the extended portion and electrically connected to the other side of the metal member and electrically connected to the ground layer, and the first radiator comprising at least a part of the metal member; and a feed line, having one end electrically connected to the feed point and another end electrically connected to the wireless communication chip, and being configured to transmit a first wireless signal to the feed point to feed into the first radiator.
