Problems solved by technology

[0005] However, existing planar antennas have poor radiation patterns, low antenna gain, and cannot adjust the angle to align with the radiation field direction
[0006] If you want to enhance its gain and radiation mode, you must add an external antenna when using it, which will cause trouble and inconvenience in use
[0007] Due to the above reasons, the applicability of the existing wireless network card and its antenna is not good

Abstract

The invention relates to a USB wireless network card with an external antenna device, comprising a USB wireless network card unit, an angle regulating unit and an antenna unit. The USB wireless network card unit comprises a USB plug body, a circuit board and a shell. The angle regulating unit comprises a rotary seat and an angle regulating sleeve body, wherein a first angle regulating mechanism is arranged between the rotary seat and the shell; and a second angle regulating mechanism is arranged between the rotary seat and the angle regulating sleeve body. The antenna unit comprises an antenna body and an antenna sheath, wherein the antenna body is connected to the circuit board after passing through the angle regulating unit, and the antenna sheath is sleeved outside the antenna body andconnected with the angle regulating unit. The first and second angle regulating mechanisms which are provided with the external antenna unit and the angle regulating unit enhance the increment and the radiation mode of a portable electronic device to the wireless signal receiving and transmission.

Description

technical field [0001] The invention relates to a USB wireless network card, in particular to a USB wireless network card with an external antenna device. Background technique [0002] Due to the vigorous development of wireless communication technology and the Internet, wireless information products formed by combining portable electronic devices (such as notebook computers, PDAs, etc.) with wireless communication equipment have been widely developed and used. For example, if a notebook computer is equipped with a wireless network card and an antenna, it can use wireless communication and the Internet to achieve the function of wirelessly sending and receiving information, providing a very convenient use function. [0003] The existing wireless network card can be built into the host of the portable electronic device, or plugged into an external slot of the portable electronic device. As far as external plug-in wireless network cards are concerned, since portable electroni...
