Abstract
An antenna and associated magnetic preamplifier for use with UHF and Microwave wireless telecommunications devices operating at frequencies of greater than 0.3 gigahertz. The antenna may include a plurality of concentric loops about a core. The antenna may be made of a conductor wound helically about an air core with a circumference and a number of loops, and the spacing of the loops chosen based on the desired frequency of communication. The antenna may include a plurality of loops of conductor about a core with a ferrite rod positioned within the core. The antenna may be omnidirectional and provide a high gain at the desired frequency of communication. The magnetic preamplifiers may be based on either resonant or ferrite material-enhanced amplification. Resonant and ferrite enhancements may also be used in combination.
