Detailed Description

Referring to fig. 1, the high-gain omni-directional WIFI antenna provided in this embodiment includes a phase converter 1, a first radiation surface 2 and a second radiation surface 3 are respectively coupled in series at two ends of the phase converter 1, the lengths of the first radiation surface 2 and the second radiation surface 3 are equal, the second radiation surface 3 includes two radiation surface monomers coupled through a feed probe, the feed probe 4 includes a patch 41 coupled with one radiation surface monomer and a microstrip line 42 coupled with the other radiation surface monomer, and the patch 41 and the microstrip line 42 are arranged in a T-shaped structure.

It should be noted that, in the present embodiment, the phase converter 1 is provided as a 180-degree phase converter 1. The structure of the existing WIFI antenna is improved, the two radiating surfaces are serially coupled and fed through the phase converter 1 to form a binary array, the gain of the antenna is greatly improved, and the phase converter 1 positioned between the two radiating surfaces can enable the currents of the radiating surfaces on two sides to be in the same direction. By coupling the two radiation surfaces at the two ends of the phase converter respectively, the radiation surfaces at the two ends and the middle phase converter 1 can be separated, electromagnetic waves generated by the two radiation surfaces are better superposed on the horizontal plane, and the phase converter 1 has small influence on the electromagnetic waves. Meanwhile, the isolation between the antenna and other antennas can be improved through a coupling mode, the electromagnetic interference of the antenna is reduced, and other electromagnetic waves can be possibly received by the radiation surface but can not necessarily pass through the coupling position to the input end of the antenna. It should be noted that if the feed is not coupled, the antenna has a long length, and low-frequency resonance is generated, and after the feed is coupled, the low-frequency resonance is not generated, and no noise exists.

The impedance can be adjusted by adjusting the line width of the radiation surface and the coupling pogo pin, the line width is about wide, the lower the impedance is, the narrower the line width is, and the higher the impedance is, in this embodiment, the length of the microstrip line 42 is 15mm, and the width is 1.8 mm. The patch 41 has a length of 6mm and a width of 3 mm.

Further, the lengths of the first radiation surface 2 and the second radiation surface 3 are set to 0.5 waveguide wavelength, respectively. The current directions of the phase converter 1 and the two radiating surfaces are opposite.
