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.

Abstract: Exemplary embodiments of apparatus and methods relating to antenna multiplexers and demultiplexers are disclosed. In exemplary embodiments, antenna multiplexers include two or more inputs for receiving a corresponding number of signals from multiple antennas. The antennas may include a cellular antenna (e.g., world cell antennas or cellular antenna operable within one or more of AMPS/GSM850, GSM900, GSM1800, PCS/GSM1900, UMTS/AWS, GSM850, GSM1900, AWS, LTE, AMPS, PCS, EBS, BRS, WCS, etc.). The antennas may also include AM/FM antennas, SDARS antennas, GPS antennas, and/or antennas combining the preceding. Exemplary antenna multiplexers also include an output for simultaneously outputting the combined signals received by the multiplexer. Demultiplexers for receiving such combined signals and outputting each signal via a separate output are also disclosed.
