Abstract

Exemplary embodiments are provided of molding designs and methods for helical antennas. In an exemplary embodiment, a method generally includes placing an antenna element between a top mold core and a first bottom mold core, and injecting molding material into a first mold cavity defined by at least the top mold core, thereby forming a top portion of a helical antenna housing and two opposite side portions of the helical antenna housing. The method also includes removing the first bottom mold core and placing a second bottom mold core about the antenna element, and injecting molding material into a second mold cavity defined by at least the second bottom mold core, thereby forming a bottom portion of the helical antenna housing.
