A dual-frequency dual-stream high-gain antenna

Abstract

The invention discloses a double-frequency double-current high gain antenna. The antenna comprises a first PCB board, a second PCB board and a third PCB board used for being grounded. The antenna further comprises a coaxial line used for transmitting signals. The first PCB board comprises a first low frequency oscillator, a second low frequency oscillator and a low frequency feed connecting line. The first PCB board also comprises a first high frequency oscillator, a second high frequency oscillator, a third high frequency oscillator and a fourth high frequency oscillator. The second PCB board is provided with a high frequency feed connecting line. The first high frequency oscillator, the second high frequency oscillator, the third high frequency oscillator and the fourth high frequency oscillator are connected through the high frequency feed connecting line. The third PCB board is connected with the first PCB board and the second PCB board. According to the invention, high and low frequency oscillators share the space and the high and low frequency feed connecting line are not co-planar, so that the high gain double-frequency double-current antenna is formed.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a dual-frequency and dual-stream high-gain antenna. Background technique [0002] With the popularity of smart phones, users' demand for data traffic increases, the traditional mode of working in the 2.4GHz frequency band cannot meet market demand, and the mode of working in the 5GHz frequency band has emerged as the times require. [0003] However, the 2.4GHz and 5GHz frequency bands have their own advantages and disadvantages. 2.4GHz has strong penetration ability, but the data bandwidth is small, and 5GHz data bandwidth is large, but the penetration effect is poor. In order to ensure long-distance coverage and short-distance data bandwidth, more and more outdoor APs require dual-band mode. [0004] The dual-band mode of a directional AP needs to be mapped to the antenna, that is, a dual-band directional antenna is required. Contents of the invention [0005] T...
