ABSTRACT:
An antenna system is disclosed that includes a mast, waveguides positioned about the mast, and a feed system positioned external to the mast and between adjacent waveguides, such the feed system can be easily serviced. The waveguides include spherical radiator elements that are easy to manufacture, and thus reduce the cost associated with wideband cavity-backed antennas.
