Embodiment
Invention thought of the present utility model is：
The utility model provides a kind of easy processing and the WLAN anti-interference antennas with noiseproof feature, and it includes：Antenna
Cover, dielectric-slab, planar slot antenna, microstrip line, bottom plate and feed connection.The utility model is radiated using the sensing of slot antenna
The reflex of characteristic and bottom plate, makes the direction that antenna is weaker compared to one radianting capacity of general omnidirectional antenna formation, will
The direction plays a part of weakening interference towards interference source.
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 anti-interference antennas, including：It is antenna house 1, dielectric-slab 2, planar slot antenna 3, micro-
Band 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 is that a width is 3mm, and radius is 20mm 240 degree of annular slots.Annular slot
It is shaped as an inverted " C " shape.The opening edge of annular slot is vertically arranged.Parameter values in Fig. 3 are respectively：Rh=20mm；
