Abstract

The invention provides a double-band L-shaped inflected antenna. The size of the antenna is only 110mm*40mm*25mm, but the antenna can cover the bands of LTE800, CDMA800 (band 5 / 6 / 18) 0.824-0.91GHz, LTE2300, WLAN 2.45GHz and 2.23-2.50GHz; the antenna has the characteristics of small size and stable radiation; in addition, the antenna is simple in structure and low in cost, realizes wide bands only using simple copper metal antenna sections, and thus has a broad market prospect.

Description

technical field [0001] The invention relates to a dual-band L-shaped folded antenna, in particular to a dual-band L-shaped folded antenna applicable to LTE, CDMA and WLAN, and belongs to the technical field of antennas. Background technique [0002] Antenna is a component that radiates and receives electromagnetic wave energy in systems such as wireless communication, radio and television, satellite communication, navigation, and cordless telephone. role. With the rapid development of modern wireless communications, especially the wide application of WLAN (Wireless Local Area Network), LTE (Long Term Evolution) and CDMA (Code Division Multiple Access), people have higher and higher requirements for antenna performance. [0003] WLAN (Wireless Local Area Network) is a network established within a certain local area using wireless communication technology. It is the product of the combination of computer network and wireless communication technology. ) function. [0004] LT...
