Problems solved by technology

[0007] Although the dual-frequency planar inverted "F" antenna can meet the requirements of the frequency band, due to its own radiation characteristics, its radiation field will produce blind spots, resulting in the inability to send and receive signals in some directions

Embodiment Construction

[0017] figure 1 with figure 2 It is a preferred embodiment of the multi-frequency antenna 10 of the present invention, which includes a first antenna 1 and a second antenna 2 formed by punching and bending a sheet metal. The first antenna 1 has a first radiating portion 11 , a second radiating portion 12 , a third radiating portion 13 , a first feeder access portion 14 , a first connecting portion 15 and a grounding portion 16 . Wherein the first radiation part 11 works in the lower frequency band of 2.4GHz of the IEEE802.11a standard, the second radiation part 12 works in the higher frequency band of 5GHz of the IEEE802.11b / g standard, and the third radiation part 13 is a high-frequency radiation It can further expand the bandwidth of the high-frequency radiation part.

[0018] The first radiating part 11 includes a first radiating arm 111 shared with the second radiating part 12, a second radiating arm 112 extending from one end of the first radiating arm 111 perpendicula...

Abstract

This invention discloses a multi-frequency antenna formed by punching and bending a metal plate including a frist antenna and a second antenna, either of which has a low frequency radiation part working at 2.4GHz and a high frequency radiation part working at 5GHz, in which, the low frequency radiation parts of the two antennas are not at the same plane or on a same line, so the radiation fields of the low radiation parts of the first and second antennas are not in a same plane or on a same line and multi-frequency antenna is made up greatly in the radiation blind region of low frequency radiation band.

Description

【Technical field】 [0001] The invention relates to a multi-frequency antenna, in particular to a multi-frequency antenna used in notebook computers or other electronic terminals. 【Background technique】 [0002] With the rapid development of mobile communications, people increasingly hope that they can access the Internet anytime and anywhere with a notebook computer or other portable terminals. The wireless access mode based on GPRS (General Packer Radio Service, general packet radio service) and WLAN (Wireless Local Area Network, wireless local area network) satisfies this requirement of people to a certain extent. GPRS is a wireless network with wide area coverage, and its data transmission rate is about 30Kbps to 50Kbps, while WLAN is a wireless network with local area coverage, and its data transmission rate can reach 11Mbps (based on 802.11b technology). People choose different wireless network cards and cooperate with portable terminals such as notebook computers to ac...
