BROADBAND ANTENNA AND WIRELESS COMMUNICATION DEVICE EMPLOYING SAME

摘要

A broadband antenna is mounted in a metal piece and includes a radiating portion, a ground portion, and a feed portion. The radiating portion includes a main portion and a plurality of radiating arms extending from the main portion in multiple directions, the radiating arms extend to contact the metal piece. The main portion, the radiating arms, and the metal piece enclose several slots. The ground portion is connected to a plurality of end portions of the radiating arms. The feed portion is connected to the metal piece and is adjacent to the radiating portion. The feed portion, the ground portion, the main portion, and the plurality of radiating arms form different current paths, thus to form different resonance nodes, thereby tender the broadband antenna to work at multi frequency bands. A wireless communication device employing the broadband antenna is also described.

主权项

1. A broadband antenna mounted in a metal piece, the broadband antenna comprising:
a radiating portion including a main portion and a plurality of radiating arms extending from the main portion in multiple directions, the radiating arms extending to contact sidewalls of the metal piece, the main portion, the radiating arms, and the metal piece enclosing several slots; a ground portion connected to a plurality of end portions of the radiating arms; and
a feed portion connected to the metal piece and adjacent to the radiating portion;wherein the feed portion, the ground portion, the main portion, and the plurality of radiating arms form different current paths, thus to form different resonance nodes, thereby tender the broadband antenna to work at multi frequency bands.
