Abstract

A method and apparatus for stacked waveguide horns using dual polarity feeds oriented in quadrature have been disclosed.

Claims

1. A method comprising:

placing a first probe at a first orientation in a first plane;

placing a second probe at a second orientation in a second plane;

locating said first probe and said second probe inside a first waveguide horn,

wherein said first plane and said second plane are substantially parallel to each other, and said first orientation and said second orientation are substantially at right angle to each other when viewed normal to said second plane;

placing a third probe at a third orientation in a third plane;

placing a fourth probe at a fourth orientation in a fourth plane; and

locating said third probe and said fourth probe inside a second waveguide horn.

2. The method of claim 1 wherein said third plane and said fourth plane are substantially parallel to each other, and said third orientation and said fourth orientation are substantially at right angle to each other when viewed normal to said fourth plane.

3. The method of claim 2 further comprising:

stacking said first horn and said second horn so that said first plane and said third plane are located in a common plane and said first orientation and said third orientation are in a common orientation.

4. An apparatus comprising:

means for building a circular horn;

means for stacking one or more circular horns into a staked circular horn array;

means for orientating one or more stacked circular horn arrays in different directions;

means for building said circular horn with a horizontal probe and vertical probe;

means for connecting one or more horizontal probes to a horizontal power divider; and

means for connecting one or more vertical probes to a vertical power divider.

5. The apparatus of claim 4 wherein said means for connecting is means for phasing said horizontal power divider and said vertical power divider to provide circular polarity.
