1. A method of designing omni-directional, broadband antennas, comprising the following steps:

  • providing at least one design parameter for a driven antenna structure as input to an algorithmic process, comprising a genetic algorithm;

    executing said algorithmic process to determine size and position of parasitic elements for combination with said driven antenna structure to create improved antenna configurations, characterized by a central antenna portion surrounded by a plurality of parasitic elements forming a sleeve configuration; and

    identifying selected of said improved antenna configurations as optimum configurations based on a determined fitness value for each improved antenna configuration.
