Description

A kind of improved microwave inductive switch antenna

Technical field

The present invention relates to microwave antenna applied technical fields, in particular to a kind of microwave inductive switch antenna.

Background technique

Microwave inductive switch is using the detector for moving object of Doppler effect principle design, it is visited in a non contact fashionWhether the position for surveying object moves, and then generates corresponding switch operation, can very easily be applied to environment and assistThe various fields such as light source control, underground parking, pathway lighting.The close circle of the projection of existing microwave inductive switch radiation beamShape, the present invention improve antenna structure, and make aerial radiation wave beam is projected as ellipse, increase longitudinal probing away fromFrom, reduce lateral investigative range, more suitable for the regions such as corridor, corridor induction detect.

Summary of the invention

The purpose of the present invention is to provide microwave inductive switch antenna, radiation beam is projected as ellipse, more applicableIn regions such as corridor, corridor, parking lots to the Lighting control of mobile object.

To achieve the above object, the technical solution adopted by the present invention are as follows:

A kind of improved microwave inductive switch antenna, the indentation antenna including 2 radiating elements and connection radiating element, loadUnit, connecting line, copper clad plate.

In order to change the shape of microwave inductive switch radiation beam projection, increase by 2 radiation on indentation radiating antennaUnit, the shape that the position of appropriate selective radiation unit can be such that microwave inductive switch radiation beam projects become in the horizontal directionIt is narrow, it is broadening in vertical direction, thus the shape of microwave inductive switch radiation beam projection is ellipse.

In order to improve the matching of antenna, increase a loading unit, while the length and width of loading unit at the antenna back sideCertain control action is risen to the shape of microwave inductive switch radiation beam projection.

It is connected between antenna back side loading unit and copper clad plate with connecting line, connecting line plays inductance, and antenna can be realExisting dual band operation.

Compared with the prior art, a kind of improved microwave inductive switch antenna, antenna pattern half power lobe width exist64 degree of horizontal direction, at 70 degree of vertical direction.
