ABSTRACT The design of metal patch antennas was presented along with performance data for Juno MWR flight model antenna arrays. Metal patches are supported by a large diameter metallic column and contain no dielectric. This makes metal patches attractive for applications where dielectrics are problematic, such as environments prone to electrostatic discharge, high radiation, and very high frequency operation (where dielectric losses can be appreciable). While not demonstrated in this paper, single layer metal patches can be tuned for wide bandwidth commensurate with that of stacked patch antennas. Additionally, metal patches can be designed with symmetrical feeds and symmetrical geometries for better pattern performance and dual polarization.
