ABSTRACT:
A low profile ceramic choke for global positioning antenna systems having a ceramic ring with a plurality of concentric segments arranged in coaxial relationship about a center occupied by a circular antenna. The segments are spaced apart from each other and may be housed in a metal enclosure. The top surface of the ceramic ring and the enclosure are of frustro-conical configuration to provide for moisture elimination. The choke is less bulky and is smaller in size and the use of ceramic as a high dielectric constant material promotes fabrication by molding and mass production techniques.
