The present invention is an improved antenna system. In an embodiment of the invention, the antenna system of the present invention may be a dielectric resonator antenna which may include a dielectric cap that may surround a plurality of feed probes. The antenna system may be suitable for coupling to a projectile whereby the dielectric cap forms a front end, or nose, of the projectile. The plurality of feed probes may produce orthogonal vector components of a field to provide circular polarization. Additionally, feed probes may be optimally spaced within the dielectric cap to ensure the phase center of the antenna system may be co-located with a platform axis of rotation whereby no carrier phase rollup compensation may be required.
