[0059] Please refer to Picture 9 , Picture 9 Shown as a schematic diagram of a planar antenna according to the second embodiment of the present invention. The second embodiment differs from the first embodiment in that the shape of the short-circuit portion 234 of the planar antenna 23 is different from that of the short-circuit portion 134 of the planar antenna 13, and the fourth interval H is different from the fifth interval hs.

[0060] Please also refer to Picture 10 , Picture 11 and Picture 12 , Picture 10 , Picture 11 and Picture 12 Shown are the measurement diagrams of the voltage standing wave ratio of the planar antenna 23 under different size designs. Picture 10 Shown as the voltage standing wave ratio (Voltage Standing Wave Ratio, when the third distance L1=3.4, the first distance L2=6, the fourth distance H=6, the second distance g=0.4, and the fifth distance hs=1.6 VSWR); Picture 11 Shown as the voltage standing wave ratio when the third distance L1=4.4, ...

Abstract

The invention relates to a wireless communication device and a flat plane antenna thereof. The wireless communication device comprises a connecting port, a printed circuit board and a flat plane antenna, wherein the printed circuit board is connected to the connecting port, and the flat plane antenna is formed on the printed circuit board; the flat plane antenna comprises a radiation part, a short circuit part and a feed-in part; the feed-in part is connected to the radiation part and the short circuit part; and the radiation part and the short circuit part are bent, so that the radiation part, the short circuit part and the feed-in part are distributed in one rectangular region.

Description

Technical field [0001] The present invention relates to a wireless communication device and a planar antenna thereof, and particularly relates to a reduced-size wireless communication device and a planar antenna thereof. Background technique [0002] With the advancement of computers and wireless communication technologies, wireless area networks (WLAN) have 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, current electronic devices tend to be light, thin, short, and small. Therefore, the area of ​​the USB wireless network card is also limited to the size of a USB flash drive. Therefore, how to reduce the area occupied by the antenna on the printed circuit board has become an urgent problem to be solved. Summary of the invention [0004] The present invention relates to a wireless communication device and a planar antenna ther...
