Problems solved by technology

However, some frequency bands of different standards overlap each other, such as wireless local area network (WLAN, 2.4GHz / 5GHz) and wireless metropolitan area network (WiMAX, 2.3-2.4GHz, 2.5-2.7GHz, 3.3-3.8GHz), If two antennas are used separately, it will cause a waste of space, so we need a solution to integrate the antennas used for the two antenna network frequency bands into one antenna, so as to save space

Abstract

The invention discloses a multi-frequency antenna. The antenna comprises a grounding part; a connecting sheet metal which extends from the grounding part and forms a slit with the grounding part; a conductive sheet metal which extends from the grounding part; a first radiation sheet metal which is connected with the conductive sheet metal and extends along a first direction; a second radiation sheet metal which is connected with the first radiation sheet metal and extends along a second direction opposite to the first direction; and a third radiation sheet metal which extends from one end of the connecting sheet metal, wherein, the conductive sheet metal is wider than the first radiation sheet metal and the third radiation sheet metal, and the first radiation sheet metal is wider than thesecond radiation sheet metal.

Description

【Technical field】 [0001] The present invention relates to a multi-frequency antenna, in particular to a multi-frequency antenna used in mobile electronic equipment. 【Background technique】 [0002] With the advancement of electronic technology, more and more electronic devices are equipped with wireless transceivers for wireless transmission of signals, so antenna integration is a trend. In modern wireless communication, multiple wireless communication standards coexist, making it necessary to integrate multiple antennas in one electronic device to adapt to the transmission and reception of signals in different frequency bands under multiple transmission standards. Due to the trend of miniaturization of modern electronic equipment, especially the limited internal space of mobile electronic equipment, the current industry tends to integrate multiple antennas for different frequency bands into one antenna to reduce the volume of the antenna and make it occupy less space in mobi...
