Abstract
This application is directed to an apparatus for creating microwave radiation patterns for an object detection system. The apparatus includes a waveguide conduit having first slots at one side of the conduit and corresponding second slots at an opposite side of the conduit. The waveguide conduit is coupled to a microwave source for transmitting microwaves from the microwave source through the plurality of first slots. A plunger is moveably positioned in the waveguide conduit from one end thereof. The plunger allows the waveguide conduit to be tuned to generally optimize the power of the microwaves exiting the first slots. Secondary plungers are each fitted in one of the second slots to independently tune or detune microwave emittance through a corresponding first slot.
Claims12
An apparatus for creating microwave radiation patterns for an object detection system, comprising:
- a waveguide conduit having a plurality of first slots at one side of the conduit and a plurality of corresponding second slots at an opposite side of the conduit, said waveguide conduit being coupled to a microwave source for transmitting microwaves from the microwave source through the plurality of first slots;
- a plunger moveably positioned in the waveguide conduit from one end thereof, said plunger allowing the waveguide conduit to be tuned to generally optimize the power of the microwaves exiting the first slots;
- and
- a plurality of secondary plungers, each fitted in one of said plurality of second slots to independently tune or detune microwave emittance through a corresponding first slot.
The apparatus of claim 11, wherein the waveguide conduit has a circular shape or a helical shape.
