Embodiment Construction

[0016] see figure 1 and figure 2 , a preferred embodiment of the present invention provides an antenna assembly 100, which is applied in a wireless communication device 200 such as a mobile phone.

[0017] The antenna assembly 100 includes a substrate 10 , a ground plane 20 , a feeding point 30 , a first radiator 40 , a second radiator 50 and a connecting portion 60 . The wireless communication device 200 includes a housing 220 made of non-conductive material such as plastic. The housing 220 constitutes an accommodating space (not shown) for accommodating the antenna assembly 100 .

[0018] In this embodiment, the substrate 10 is a circuit board of the wireless communication device 200, which is made of epoxy resin fiberglass (FR4). The substrate 10 is substantially a flat rectangular parallelepiped and includes a top surface 12 , a first side 14 and a second side 16 . The first side 14 and the second side 16 are perpendicular to each other and are vertically connected to ...

Abstract

The invention provides an antenna assembly and a wireless communication device applied with the antenna assembly. The antenna assembly comprises a base board, a grounding face, a first radiation body and a second radiation body. The grounding face is arranged on the base board and is used for providing ground connection for the antenna assembly. The first radiation body is connected on the base board and is used for sending and receiving a radio signal with a first center frequency. The second radiation body forms a portion of a housing of the wireless communication device and is connected with the grounding face. The second radiation body is coupled with the first radiation body so as to send and receive a radio signal with a second center frequency together. The antenna assembly helps to reduce the dimension of an antenna and is benefit for the wireless communication device to be in miniaturization development.

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,...
