Abstract

The invention discloses a double-frequency inverted-F-shaped antenna which is applied to a notebook computer and comprises a grounding metal face and an oscillator, wherein a grounding point is arranged on the grounding metal face; a feeding point is arranged on the oscillator and is connected with the grounding point on the grounding metal face through a coaxial cable, one end of the oscillator is a low-frequency oscillator, the other end of the oscillator is a high-frequency oscillator, a common terminal of the low-frequency oscillator and the high-frequency oscillator is provided with a short-circuit loading arm, one end of the short-circuit loading arm is connected with the grounding metal face, and the other end of the low-frequency oscillator is of a bent shape. As the low-frequency oscillator of the double-frequency inverted-F-shaped antenna is of the bent shape, the size of the antenna is decreased, and the requirement for the development trend of the mechanism design of the notebook computer is met.

Description

【Technical field】 [0001] The invention relates to a dual-frequency inverted-F antenna, in particular to a small-sized dual-frequency inverted-F antenna which adopts antenna meander technology to reduce the size of the antenna. 【Background technique】 [0002] The informatization of modern society has higher and higher requirements on communication technology, and the development of communication technology is changing with each passing day. Wireless communication is a main communication form of modern communication, and wireless local area network is a kind of wireless communication technology that is used more and more widely. With the use of wireless local area network, wireless local area network antenna has become a necessary accessory. At present, most of the wireless LAN antennas of notebook computers use inverted F-type antennas. Due to the use of dual-band (2.4GHz / 5GHz), the volume of the antenna body is basically about 20mm*30mm*0.2mm. Due to the pressure of the de...
