Zusammenfassung: | 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 radiator elements that are easy to manufacture, and thus reduce the cost associated with wideband cavity-backed antennas. Further, adjustable disc-like and spherical radiating elements for exciting the fields in the waveguides are also disclosed. DC voltage buildup on the radiating elements are grounded by an easily attachable coaxial structure. |
