Problems solved by technology

It increases the production cost of the antenna device, and also increases the overall volume of the antenna device, thus occupying a large part of the space in the wireless communication device, which is not conducive to the development trend of wireless communication devices in the direction of thinner and lighter
However, the limited space in mobile phone products reduces the height of the antenna and affects the radiation characteristics of the overall antenna. It is difficult to ensure a good communication effect in the daily communication process

Embodiment Construction

[0015] see figure 1 , the wireless communication device 100 of the present invention may be a mobile phone, a palmtop computer, etc., and this embodiment is described by taking a mobile phone as an example. The wireless communication device 100 includes a substrate 10, a support structure 20, an audio socket 30 and an antenna structure 40. The antenna structure 40 is arranged on the support structure 20 to send and receive radio signals, so that the wireless communication device 100 can work on BT / Wi -Fi (2400-2484MHZ, 5200-5800MHZ) two frequency bands. The audio socket 30 is installed in the support structure 20 , the support structure 20 is located on one side of the substrate 10 , and the audio socket 30 is connected to the substrate 10 through the antenna structure 40 .

[0016] The substrate 10 is roughly a rectangular printed circuit board (Printed Circuit Board, PCB). In this embodiment, the size of the substrate 10 is 131.6x66.8x10mm 3 , on which a headroom 11 and a ...

Abstract

The invention provides an antenna structure. The antenna structure is disposed on one side of a substrate. The antenna structure comprises an elastic piece, a first radiating body, a second radiating body and a connection part. The connection part is provided with a feed-in point and a grounding point, the first radiating body and the second radiating body are respectively connected with the feed-in point and the grounding point on the connection part, the connection part is connected with the substrate, the first radiating body and the second radiating body are disposed at an interval, the elastic piece is disposed on the first radiating body, and the first radiating body is coupled with the second radiating body through the elastic piece. The antenna structure obtains a first working frequency through a coupling effect generated by the first radiating body, the elastic piece and the second radiating body, and a second working frequency is obtained through a frequency multiplication effect by the first radiating body and the elastic piece. The antenna structure is reasonable in design and effectively saves an internal space of a mobile phone.

Description

technical field [0001] The present invention relates to an antenna structure, in particular to a coupled antenna structure and a wireless communication device using the antenna structure. Background technique [0002] As the design of wireless communication products develops towards thinner and lighter, consumers have increasingly stringent requirements for product appearance. Antenna devices are one of the most important components in wireless communication products such as mobile phones. When mobile phones become thinner and lighter, planar The design of the type antenna came into being, thus saving the internal space of the mobile phone. Bluetooth (BT) and Wireless Fidelity (WIFI) are two widely used wireless communication systems. At present, most of the wireless communication devices having both BT and WIFI communication functions must also be equipped with two corresponding antennas to send and receive signals used by the two systems respectively. The production cost...
