Abstract
A dielectrically-loaded multifilar helical antenna has a ceramic cylindrical core and, on the core outer surface, coextensive generally helical conductors arranged in an opposing configuration. Located on an end surface of the core is a feed connection nodes and a connection structure connecting the helical conductors to the feed connection nodes. The connection structure comprises, as a conductive coating of the core end surface, conductive paths linking a respective helical conductor and a respective feed connection node, the connection structure further comprising a series reactive link in one conductive path and a shunt reactive link interconnecting the feed connection nodes, one of the reactive links being inductive and the other being capacitive to form a matching network.
