Embodiment
Invention thought of the present utility model is：
The utility model provides a kind of easy processing and the antenna with noiseproof feature, and it includes：Antenna house, dielectric-slab,
Planar slot antenna, microstrip line, bottom plate and feed connection.Sensing radiation characteristic and bottom of the utility model using slot antenna
The reflex of plate, makes the direction that antenna is weaker compared to one radianting capacity of general omnidirectional antenna formation, by direction direction
Interference source, plays a part of weakening interference.
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 anti-interference antenna, including：Antenna house 1, dielectric-slab 2, planar slot antenna 3, microstrip line
4th, 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 a semicircle gap and a rectangular aperture, one end of rectangular aperture and semicircle
The straight flange center in gap is connected, the length of rectangular aperture and wide respectively 22mm and 4mm, and the radius in semicircle gap is 12mm.It is described
The long side of rectangular aperture is horizontally disposed with, and the straight flange in the semicircle gap is vertically arranged.Parameter values in Fig. 3 are respectively：Rh=
12mm；H1=10mm；H2=22mm.
