Antenna system and method
View Patent ↗A radiator coupled to an antenna patch disposed along a first end of the radiator, said patch disposed on an insulator. A ground plane is connected to the insulator and a radome is disposed opposite a second end of the radiator. The radome may have a region presenting a convex surface towards the radiator, and the radome has a second region presenting a concave surface towards the radiator. The first end of the conical radiator is the apex of the cone. A ground plane is included and a portion of the ground plane is a planar surface and another portion extends away from the planar portion towards the radome. Also disclosed is a method for forming a radiation pattern by shaping the radome to effectuate a predetermined radiation pattern using localized convex and concave surfaces positioned on the radome at different points in relation to the conical radiator.
1. A method comprising:
disposing an dielectric insulator on a ground plane;
disposing a patch on the insulator;
coupling a radiator on the patch;
disposing at least a portion of a radome opposite the patch, a portion of said radome presenting a convex surface towards the radiator
determining a radiation pattern for the radiator and radome, and
positioning the convex surface to alter the radiation pattern.
2. The method of claim 1 wherein the step of determining includes calculating the radiation pattern from the dimensions of the radome, ground plane and radiator.
3. The method of claim 1 wherein the step of determining includes measuring the radiation pattern.
4. The method of claim 1 further comprising:
positioning one or more concave portions on the radome with the affect that the concave portions substantially alter the radiation pattern of the device.
5. The method of claim 1 wherein the radiator is conical.
6. The method of claim 1 further comprising:
disposing a plurality of patches and radiators into an array.
