It is described to connect second irradiation unit 4 with reference to 1 other end of ground with reference to 1 one end of ground.
Further: the snakelike irradiation unit 2 is perpendicular including the first vertical radiant section 21, first level radiant section 22, second
Straight radiant section 23, the second horizontal radiation section 24 and third horizontal radiation section 25, the first level radiant section 22, first are vertical
It is snakelike that radiant section 21, the second horizontal radiation section 24, the second vertical radiant section 23 and third horizontal radiation section 25 are sequentially connected with composition
Irradiation unit.
It is further: the short-circuited transmission line 3 include horizontal segment 31 and vertical section 32, described 31 one end of horizontal segment with it is described
Vertical section 32 connects, and 31 other end of horizontal segment is connect with the first level radiant section 22,32 other end of vertical section
It is connect with described with reference to ground 1.
The utility model embodiment principle: the present embodiment can be 2.4Ghz two-band WIFI antenna, first level radiant section
22 be 2.4G radiant section, and for the radiant section close to feeding point, current distribution is bigger, and the impedance and radiation to antenna are more sensitive,
In actual debugging process, fine-tuning width can reach better matching effect.
First vertical radiant section 21 can be realized electric current using snakelike cabling for snakelike radiant section in 2.4G radiant section
Bending, in the case where not changing antenna performance, the effective real area for reducing antenna, so as to be applied to smaller sky
Between.The capacity effect of the component is affected, and the impedance of antenna can be adjusted by the component.
Second horizontal radiation section 24 is that the vertical radiant section 21 and second of intermediate stage connection first of 2.4G radiant section is perpendicular
Straight radiant section 23 is mainly used for extending current path, realizes total radiator of 1/2 wavelength.
Second vertical radiant section 23 is snakelike radiant section and the first vertical radiant section 21 is similar adopts in 2.4G radiant section
With snakelike cabling, electric current bending can be realized, in the case where not changing antenna performance, the effective practical face for reducing antenna
Product, so as to be applied to smaller space.The capacity effect of the component is affected, and the resistance of antenna can be adjusted by the component
It is anti-.
Third horizontal radiation section 25 be 2.4GHz radiant section latter end, first level radiant section 22, the first vertical radiant section 21,
Second horizontal radiation section 24, the second vertical radiant section 23 constitute snakelike irradiation unit, and total length may be slightly larger than 1/2 wavelength, the end
The frequency shift (FS) of antenna can be effectively controlled, current distribution is similar with half-wave dipole, antenna pattern and half-wave dipole subclass
