摘要： A spiral, helical antenna is configured to produce a generally circular polarized radiation pattern covering a range of frequencies, over a ground plane. The antenna is comprised of a spring-like spiral conductor that may be held in compression by a size and shape regulating outer nonconductive membrane. The assembly may be compressed and or extended to adjust the antenna for best performance in a particular situation. The assembly may be compressed into a generally flattened state for storage and or transportation, and extended at a later time for use. Accurate antenna dimensions and good performance are afforded by the use of high quality spring materials in conjunction with precise membrane dimensions.

摘要： A fin-type planar antenna and a deployable dipole antenna are combined into a system as a diversity fin antenna to reduce or eliminate cross polarization fades and dropouts common to wireless audio systems used in theatres, churches and convention centers. A dual feedline connects the diversity fin antenna system to a diversity-equipped receiver in a convenient and rapid manner. The antenna system features broad bandwidth, resistance to deep nulls or fades caused by cross polarization, and an air space dielectric covering provides resistance to detuning in the presence of rain, or touching objects.
