Problems solved by technology

[0003] At present, the 3G modules configured by the notebook computers produced by the manufacturer are all downward compatible and contain the GSM (Global System for Mobile Communications) system, so the working frequency bands that the modules can use are: GSM900 (880MHz~960MHz), DSC1800 (1710MHz~1880MHz), WCDMA2100 (1920MHz~2170MHz), this puts forward higher requirements for the built-in antenna of the notebook computer, the antenna must meet the requirements of the three frequency bands at the same time, and most of the current mobile communications use single GSM antenna or WCDMA2100 frequency band antenna, Does not meet the requirements of all three frequency bands at the same time

Embodiment Construction

[0020] In order to have a further understanding of the purpose, structural features and functions of the present invention, the detailed description is as follows in conjunction with the accompanying drawings:

[0021] see figure 1 , figure 2 As shown, they respectively show a schematic diagram of the tri-band antenna of the present invention at one angle in a preferred embodiment, and a schematic diagram of the tri-band antenna of the present invention at another angle in a preferred embodiment. The tri-band antenna of the present invention, in this embodiment, uses phosphor bronze as the base material, and is manufactured by mold integral molding. The tri-band antenna includes:

[0022] ground plane 400;

[0023] The first vibrator 100 has several cracks 110 on its edge, and the several cracks 110 increase the effective length of the first vibrator 100, thereby reducing the resonant frequency of the first vibrator 100 to a required frequency point, and the several cracks ...

Abstract

The invention discloses a triple-band antenna, which comprises a ground plane, a first vibrator, a second vibrator, a third vibrator and a feeder line. A plurality of cracks are formed in the first vibrator which is parallel to the ground plane. The second vibrator is arranged coplanarly with the first vibrator, and is parallel to the ground plane. A slot is formed between the second vibrator and the first vibrator. The third vibrator is arranged coplanarly with the first and second vibrators, and is parallel to the ground plane. A cross slot is formed in the third vibrator. The third vibrator and the second vibrator are connected with the ground plane through a connecting part. The feeder line comprises an inner core wire and a shielding layer. The shielding layer is connected with the ground plane. The inner core wire is connected to the second or third vibrator. According to the triple-band antenna, the cracks are formed in the first vibrator, so that the resonant frequency of the low-frequency vibrator is lowered to a required frequency point; and in addition, the cross slot is reserved in the third vibrator, so that the width of the triple-band antenna is increased, and the high-frequency vibrator meets the operation requirements of a required band. Therefore, the good signal transmission and receiving effects of the triple-band antenna are ensured.

Description

【Technical field】 [0001] The invention relates to an antenna, in particular to a tri-frequency antenna capable of simultaneously working in three frequency bands of GSM900, DCS1800 and WCDMA2100. 【Background technique】 [0002] In recent years, with the rapid development of personal communication and mobile communication all over the world, there has been an upsurge of using 3G worldwide. Notebook computers have been widely used as a tool for mobile office communication. In order to better cater to market consumption concepts, notebook computers have also begun to configure 3G functions. WCDMA (Wideband Code Division Multiple Access) is a 3GPP (Third Generation Mobile Communications Cooperation project team), based on the third-generation mobile communication system based on GSM / MAP as the core network and UTRAN (terrestrial radio access network) as the wireless interface. [0003] At present, the 3G modules configured by the notebook computers produced by the manufacturer ...
