Abstract
A reflector for an antenna includes a first shaped region, wherein a curvature of the first shaped region is defined by a corresponding scan angle, and a second shaped region, wherein a curvature of the second shaped region is based on a corresponding scan angle. The curvature of the first shaped region is different than the curvature of the second shaped region.
Claims20
A method for manufacturing a reflector for an antenna, the method comprising:
- tracing a plurality of electromagnetic energy rays from a plurality of scan directions;
- shaping a plurality of reflector regions based on the traced plurality of electromagnetic energy rays, wherein the plurality of reflector regions has different curvatures corresponding to the scan directions;
- performing a local optimization of the curvatures of the plurality of reflector regions to yield a locally optimized plurality of reflector regions;
- blending the locally optimized plurality of reflector regions to yield a blended plurality of reflector regions;
- performing a global optimization of the blended plurality of reflector regions to yield a globally optimized plurality of reflector regions;
- generating an overall shape using the globally optimized plurality of reflector regions;
- and forming a reflector based on the overall shape.
