Abstract

The invention provides an antenna assembly which comprises a base plate, a ground plane, a feed-in portion, a first radiation portion, a second radiation portion and a third radiation portion. The ground plane is arranged on the top surface of the base plate, the antenna assembly can be grounded by the aid of the ground plane, the peripheral edge of the ground plane is hollowed out to form the first radiation portion, the second radiation portion and the third radiation portion respectively, the feed-in portion comprises a plurality of feed-in points, the feed-in points are respectively arranged on the first radiation portion, the second radiation portion and the third radiation portion, the first radiation portion is divided into a first radiation section and a second radiation section, the first radiation section is used for transmitting and receiving wireless signals in first frequency bands, the second radiation section is used for transmitting and receiving wireless signals in second frequency bands, the second radiation portion is used for transmitting and receiving wireless signals in third frequency bands, and the third radiation portion is used for transmitting and receiving wireless signals with fourth center frequencies, so that a plurality of slot antennas can be formed. The invention further provides a wireless communication device with the antenna assembly.

Description

technical field [0001] The invention relates to an antenna component and a wireless communication device with the antenna component. Background technique [0002] In a wireless communication device, the antenna device used to transmit and receive radio waves to transmit and exchange radio data signals is undoubtedly one of the most important components in the wireless communication device. In recent years, the emergence of various communication systems and applications using different operating frequency bands has led to the development of antenna design towards broadband antennas covering multiple system frequency bands. In order to ensure that the wireless communication device can perform signal transmission in various wireless communication systems using different operating frequency bands, the antenna device must be capable of transmitting and receiving signals of various frequencies. On the other hand, the broadband antenna generally has a relatively complex structure,...
