Specific embodiment
The present invention invention thought be:
The present invention provides a kind of WLAN antennas of easy processing, and it includes:Antenna house, dielectric-slab, planar slot antenna, micro-strip Line, base plate and feed connection.The present invention makes antenna phase using the sensing radiation characteristic of slot antenna and the reflex of base plate The weaker direction of a radianting capacity is formed compared with general omnidirectional antenna, by the direction towards interference source, is played and is weakened interference Effect.
The present invention 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, Base plate 5 and feed connection 6;
The antenna house 1 is covered on around the dielectric-slab 2 of the top of base 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 the feed connection 6 and the base plate 5 and the plane gap day Line 3 connects;The feed pin at the center of the feed connection 6 is connected with the microstrip line 4;The material of base 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 for intersecting vertically, and the intersecting position of rectangular aperture is in length At on direction 2/3, the length and width of rectangular aperture are respectively 42mm and 8mm.Two intersecting one left sides of rectangular aperture formation are big Right little 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 =8mm;H2=24mm;H3=10mm.
