Abstract

The invention discloses a printed antenna which comprises a substrate, a first ground plane, a low-frequency radiation part, a high-frequency radiation part, a first matching part and a second matching part. The first ground plane, the low-frequency radiation part, the high-frequency radiation part and the first matching part are positioned on the upper surface of the substrate. The low-frequency radiation part is connected with the high-frequency radiation part, and the first matching part extends to the high-frequency radiation part from the first ground plane. The second matching part is adjacent to the first matching part and is not overlapped with the first matching part vertically.

Description

technical field [0001] The invention relates to a printed antenna, and in particular to a printed antenna applied to a wireless network device. Background technique [0002] With the advancement of computer and wireless communication technology, Wireless Area Network (WLAN) has gradually been widely used in daily life. At present, many electronic devices can be connected to a wireless local area network through a wireless network device. The wireless network device is, for example, a universal serial bus wireless network card (USB dongle), a wireless base station (Access Point, AP) or a router (Router) [0003] Traditional wireless network devices can transmit and receive wireless signals through an external dipole antenna. Since the external dipole antenna will destroy the overall aesthetics of the appearance and require additional purchase costs, the printed antenna formed on the printed circuit board has gradually replaced the dipole antenna. [0004] However, the radi...
