[0104] Please also refer to figure 1 and figure 2 , figure 1 Shown is a top view of the dual-frequency dual-antenna structure according to the first embodiment of the present invention, figure 2 Shown is a bottom view of the dual-frequency dual-antenna structure according to the first embodiment of the present invention. The dual-band dual-antenna structure 10 is used, for example, in a wireless communication device, such as a universal serial bus (Universal Serial Bus, USB) dual-band wireless network card. The dual-frequency dual-antenna structure 10 includes a substrate 110 , an antenna 120 and an antenna 130 . The areas of the antenna 120 and the antenna 130 are preferably smaller than 10mm×10mm, for example. The substrate 110 includes a signal transmission layer 112 and a signal transmission layer 114 not coplanar with the signal transmission layer 112 . Wherein, the area of ​​the substrate 110 is, for example, the same as the size of a USB flash drive. In the firs...

Abstract

The invention relates to a double-frequency and dual-antenna structure, which comprises a substrate, a first antenna and a second antenna, wherein the substrate comprises a first signal transmission layer and a second signal transmission layer which is not coplanar with the first signal transmission layer; the first antenna is arranged on the first signal transmission layer and comprises a first U-shaped radiation assembly and a first polygon radiation assembly; the first polygon radiation assembly is arranged in an opening of the first U-shaped radiation assembly; the second antenna is arranged on the second signal transmission layer and is not superposed with the first antenna; the second antenna comprises a second U-shaped radiation assembly and a second polygon radiation assembly; andthe second polygon radiation assembly is arranged in an opening of the second U-shaped radiation assembly.

Description

technical field [0001] The present invention relates to an antenna, and in particular to a dual-frequency dual-antenna structure. Background technique [0002] With the advancement of computer and wireless communication technology, wireless area network (Wireless Area Network, WLAN) has gradually been widely used in daily life. At present, many electronic devices can be connected to a wireless local area network through a Universal Serial Bus (USB) wireless network card. [0003] However, with different wireless network standard specifications, the corresponding operating frequency bands of wireless local area networks are also different. Therefore, how to provide a USB wireless network card with dual operating frequency bands will be a very important issue. Furthermore, current electronic devices tend to be light, thin, short, and small in design. Therefore, the area of ​​the USB wireless network card is also limited to the size of a USB flash drive. In this case, the an...
