Abstract

A broadband antenna is mounted aside a metal electronic element and includes a feeding portion, a first connecting portion, a second connecting portion, a coupling portion, and a ground portion. The first radiating portion and the second radiating portion are both connected perpendicular to the feeding portion. The coupling portion is spaced from the first radiating portion and the second connecting portion. The ground portion is connected perpendicular to a middle portion of the coupling portion and adjacent to the metal electronic element. These portions cooperatively use a low frequency mode and a high frequency mode. The ground portion increases an inductance performance of the broadband antenna, thereby decreasing interference caused by the metal electronic elements. A wireless communication device employing the broadband antenna is also disclosed.

Description

technical field [0001] The invention relates to an antenna, in particular to a broadband antenna capable of suppressing interference to the antenna by other electronic components in a wireless communication device and a wireless communication device with the broadband antenna. Background technique [0002] With the development of wireless communication devices, larger screens and thinner overall appearances have become a trend. Therefore, the space reserved for antenna design by wireless communication devices is getting smaller and smaller. At the same time, due to the metal components around the antenna, such as universal serial bus (universal serial bus, USB), battery and display screen, etc., it is easy to cause greater interference or shielding effect on the antenna and reduce the transmission characteristics of the antenna. In addition, wireless communication devices have increasing requirements on antenna bandwidth, and antennas need to cover multiple frequency bands t...
