Embodiment
Invention thought of the present utility model is：
The utility model provides a kind of WLAN antennas of easy processing, and it includes：Antenna house, dielectric-slab, planar slot antenna,
Microstrip line, bottom plate and feed connection.The utility model utilizes the sensing radiation characteristic of slot antenna and the reflex of bottom plate,
Make the direction that antenna is weaker compared to one radianting capacity of general omnidirectional antenna formation, by the direction towards interference source, play and cut
The effect of weak jamming.
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Fig. 1~5, a kind of WLAN antennas, including：Antenna house 1, dielectric-slab 2, planar slot antenna 3, microstrip line 4,
Bottom plate 5 and feed connection 6；
The antenna house 1 is covered on around the dielectric-slab 2 of the top of bottom plate 5；The planar slot antenna 3 and the microstrip line 4
It is separately positioned on the both sides of the dielectric-slab 2；The outer surface of feed connection 6 and the bottom plate 5 and the plane gap day
Line 3 is connected；The feed pin at the center of feed connection 6 is connected with the microstrip line 4；The material of bottom plate 5 is conductor.
The conductor surface of the planar slot antenna 3 is close to the dielectric-slab 2；One end of the microstrip line 4 and the plane
The conductor surface connection of slot antenna 3；
The planar slot antenna 3 includes two rectangular apertures intersected vertically, and the intersecting position of rectangular aperture is in length
On direction 2/3 at, the length of rectangular aperture and it is wide be respectively 21mm and 4mm.Two intersecting one left sides of rectangular aperture formation are big
Right small X-shaped shape.The long side of the rectangular aperture is from the horizontal by 45 degree of settings.Parameter values in Fig. 3 are respectively：h1
