Abstract

The invention provides a high-gain WiFi antenna and a wireless communication terminal. The high-gain WiFi antenna comprises a metal wall beam wave unit with a trumpet-shaped opening, a reflecting plate located at the bottom of the inner side of the metal wall beam wave unit, a PCB substrate located in the metal wall beam wave unit and an onboard antenna located on the surface of the PCB substrate. The onboard antenna comprises a first radiation unit and a second radiation unit; the first radiation unit comprises a first branch knot and a second branch knot which are communicated with each other, the first branch knot is circular, and the second branch knot is semi-circular and semi-surrounds the first branch knot; the second radiation unit is circular and surrounds the first radiation unit. Electromagnetic waves in a 2.4 GHz frequency band range are generated through the onboard antenna, and when the electromagnetic waves touch the reflecting plate and the metal wall beam wave unit, the electromagnetic waves are reflected, so that the antenna gain in a fixed direction is remarkably improved; each branch knot of the onboard antenna is in the shape of a circle (ring), so that the onboard antenna has better circular polarization, the radiation performance of the antenna is ensured, the signal attenuation is smaller, and the problems of low gain and large signal attenuation of the existing WiFi antenna are solved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a high-gain WiFi antenna and a wireless communication terminal. Background technique [0002] WiFi, also known as "mobile hotspot", now almost all smartphones, tablets and laptops support WiFi Internet access, and is the most widely used wireless network transmission technology today. [0003] Usually, the antenna for realizing the WiFi communication function includes a built-in PCB antenna, a ceramic antenna, or an external antenna by connecting the antenna extension cable through the I-PEX connector. However, most of the existing WiFi antennas are omnidirectional antennas, usually with insufficient gain in a fixed direction, the signal attenuation is too large after passing through walls, and the throughput drops significantly. [0004] With the development of wireless communication technology and people's increasing wireless communication experience, WiFi is re...
