Problems solved by technology

Chinese patent announcement No. CN 2593384Y discloses a planar inverted "F" type multi-frequency antenna, which includes a radiating part with two radiating arms extending in opposite directions, a grounding part, and a connecting part connecting the radiating part and the grounding part. Although the antenna can realize multi-frequency operation, its long connection makes the whole antenna larger in size and higher in structure, thus occupying a large space inside a notebook computer or other portable electronic devices, which is not conducive to the development trend of miniaturization of electronic devices

Abstract

The invention relates to a multi-frequency antenna, used in notebook computer or other portable electric device, wherein it comprises radiator, ground part, connector connecting radiator and ground part, feedback point, feedback line and two mounting parts; the radiator comprises the first and second radiators to form one rectangle frame with one cut. The invention has small volume.

Description

【Technical field】 [0001] The invention relates to a multi-frequency antenna, in particular to a multi-frequency antenna for portable electronic devices such as notebook computers. 【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 electronic devices. 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-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 electronic devices such as noteboo...
